Feature Engineering is a process of using domain knowledge to extract and transform features from raw data. These features can be used to improve the performance of Machine Learning Algorithms.

 

Feature Engineering encompasses a diverse array of techniques, including Feature Transformation, Feature Construction, Feature Selection, Feature Scaling, and Feature Extraction, each playing a crucial role in refining and optimizing the representation of data for machine learning tasks. 

 

In this blog, we will discuss one of the feature transformation techniques called feature scaling with examples and see how it will be the game changer for our machine learning model accuracy.

In the world of data science and machine learning, feature transformation plays a crucial role in achieving accurate and reliable results. By manipulating the input features of a dataset, we can enhance their quality, extract meaningful information, and improve the performance of predictive models. Python, with its extensive libraries and tools, offers a streamlined and efficient process for simplifying feature scaling. 

 

What is feature scaling?

 

Feature scaling is a crucial step in the feature transformation process that ensures all features are on a similar scale. It is the process that normalizes the range of input columns and makes it useful for further visualization and machine learning model training. The figure below shows a quick representation of feature scaling techniques that we will discuss in this blog.

Why feature scaling is important?

 

Feature scaling is important because of several factors:

  • It improves the machine learning model’s accuracy
  • It enhances the interpretability of data by transforming features on a common scale, without scaling, it is difficult to make comparisons of two features because of scale difference
  • It speeds up the convergence in optimization algorithms like gradient descent algorithms
  • It reduces the computational resources required for training the model
  • For better accuracy, it is essential for the algorithms that rely on distance measures, such as K-nearest neighbors (KNN) and Support Vector Machines (SVM), to be sensitive to feature scales

 

Now let’s dive into some important methods of feature scaling and see how they impact data understanding and machine learning model performance.

 

Normalization

 

A feature scaling technique is often applied as part of data preparation for machine learning. The goal of normalization is to change the value of numeric columns in the dataset to use a common scale, without distorting differences in the range of values or losing any information.

 

Min-Max Scaler

 

The most commonly used normalization technique is min-max scaling, which transforms the features to a specific range, typically between 0 and 1. Scikit-learn has a built-in class available named MinMaxScaler that we can use directly for normalization. It involves subtracting the minimum value and dividing by the range of the feature using this formula.

Where,

Xi is the value we want to normalize.

Xmax is the maximum value of the feature.

Xmin is the minimum value of the feature.

 

In this transformation, the mean and standard deviation of the feature may behave differently. Our main focus in this normalization is on the minimum and maximum values. Outliers may disrupt our data pattern, so taking care of them is necessary.

 

Let’s take an example of a wine dataset that contains various ingredients of wine as features. We take two input features: the quantity of alcohol and malic acid and create a scatter plot as shown below.

 

feature scaling - normalization
Scatter plot from the wine dataset

 

When we create a scatter plot between alcohol and malic acid quantities, we can see that min-max scaling simply compresses our dataset into the range of zero to one, while keeping the distribution unchanged.

Standardization

 

Standardization is a feature scaling technique in which values of features are centered around the mean with unit variance. It is also called Z-Score Normalization. It subtracts the mean value of the feature and divides by the standard deviation (σ) of the feature using the formula:

Here we leverage a dataset on social network ads to gain a practical understanding of the concept. This dataset includes four input features: User ID, Gender, Age, and Salary. Based on this information, it determines whether the user made a purchase or not (where zero indicates not purchased, and one indicates purchased).

 

The first five rows of the dataset appear as follows:

 

dataset for standardization
Dataset for the standardization example

 

In this example, we extract only two input features (Age and Salary) and use them to determine whether the output indicates a purchase or not as shown below.

 

data for standardization

Standard Scaler

 

We use Standard-Scaler from the Scikit-learn preprocessing module to standardize the input features for this feature scaling technique. The following code demonstrates this as shown.

 

 

We can see how our features look before and after standardization below.

 

data before and after standardization

 

Although it appears that the distribution changes after scaling, let’s visualize both distributions through a scatter plot.

So, when we visualize these distributions through plots, we observe that they remain the same as before. This indicates that scaling doesn’t alter the distribution; it simply centers it around the origin.

Now let’s see what happens when we create a density plot between Age and Estimated Salary with and without scaled features as shown below.

 

density plots for standardization
Graphical representation of data standardization

 

In the first plot, we can observe that we are unable to visualize the plot effectively and are not able to draw any conclusions or insights between age and estimated salary due to scale differences. However, in the second plot, we can visualize it and discern how age and estimated salary relate to each other.

 

This illustrates how scaling assists us by placing the features on similar scales. Note that this technique does not have any impact on outliers. So, if an outlier is present in the dataset, it remains as it is even after standardization. Therefore, we need to address outliers separately.

 

Model’s performance comparison

 

Now we use the logistic regression technique to predict whether a person will make a purchase after seeing an advertisement and observe how the model behaves with scaled features compared to without scaled features.

 

 

Here, we can observe a drastic improvement in our model accuracy when we apply the same algorithm to standardized features. Initially, our model accuracy is around 65.8%, and after standardization, it improves to 86.7% 

 

When does it matter?

 

Note that standardization does not always improve your model accuracy; its effectiveness depends on your dataset and the algorithms you are using. However, it can be very effective when you are working with multivariate analysis and similar methods, such as Principal Component Analysis (PCA), Support Vector Machine (SVM), K-means, Gradient Descent, Artificial Neural Networks (ANN), and K-nearest neighbors (KNN).

 

However, when you are working with algorithms like decision trees, random forest, Gradient Boosting (G-Boost), and (X-Boost), standardization may not have any impact on improving your model accuracy as these algorithms work on different principles and are not affected by differences in feature scales

 

To sum it up

 

We have covered standardization and normalization as two methods of feature scaling, including important techniques like Standard Scaler and Min-Max Scaler. These methods play a crucial role in preparing data for machine learning models, ensuring features are on a consistent scale. By standardizing or normalizing data, we enhance model performance and interpretability, paving the way for more accurate predictions and insights.

Large language model bootcamp

Why you need synthetic data in machine learning?

In the realm of machine learning, the foundation of successful models lies in high-quality, diverse, and well-balanced datasets. To achieve accuracy, models need data that mirrors real-world scenarios accurately.

Synthetic data, which replicates the statistical properties of real data, serves as a crucial solution to address the challenges posed by data scarcity and imbalance. This article delves into the pivotal role that synthetic data plays in enhancing model performance, enabling data augmentation, and tackling issues arising from imbalanced datasets.

Improving model performance

Synthetic data acts as a catalyst in elevating model performance. It enriches existing datasets by introducing artificial samples that closely resemble real-world data. By generating synthetic samples with statistical patterns akin to genuine data, machine learning models become less prone to overfitting, more adept at generalization, and capable of achieving higher accuracy rates.

Data augmentation

Data augmentation is a widely practiced technique in machine learning aimed at expanding training datasets. It involves creating diverse variations of existing samples to equip models with a more comprehensive understanding of the data distribution.

Synthetic data plays a pivotal role in data augmentation by introducing fresh and varied samples into the training dataset. For example, in tasks such as image classification, synthetic data can produce augmented images with different lighting conditions, rotations, or distortions. This empowers models to acquire robust features and adapt effectively to the myriad real-world data variations.

Handling imbalanced datasets

Imbalanced datasets, characterized by a significant disparity in the number of samples across different classes, pose a significant challenge to machine learning models.

Synthetic data offers a valuable solution to address this issue. By generating synthetic samples specifically for the underrepresented classes, it rectifies the imbalance within the dataset. This ensures that the model does not favor the majority class, facilitating the accurate prediction of all classes and ultimately leading to superior overall performance.

Benefits and considerations

Leveraging synthetic data presents a multitude of benefits. It reduces reliance on scarce or sensitive real data, enabling researchers and practitioners to work with more extensive and diverse datasets. This, in turn, leads to improved model performance, shorter development cycles, and reduced data collection costs. Furthermore, synthetic data can simulate rare or extreme events, allowing models to learn and respond effectively in challenging scenarios.

However, it is imperative to consider the limitations and potential pitfalls associated with the use of synthetic data. The synthetic data generated must faithfully replicate the statistical characteristics of real data to ensure models generalize effectively.

Rigorous evaluation metrics and techniques should be employed to assess the quality and utility of synthetic datasets. Ethical concerns, including privacy preservation and the inadvertent introduction of biases, demand meticulous attention when both generating and utilizing synthetic data.

Applications for synthetic data

Synthetic data finds applications across diverse domains. It can be instrumental in training machine learning models for self-driving cars, aiding them in recognizing objects and navigating safely. In the field of medical diagnosis, synthetic data can train models to identify various diseases accurately.

In fraud detection, synthetic data assists in training models to identify and flag fraudulent transactions promptly. Finally, in risk assessment, synthetic data empowers models to predict the likelihood of events such as natural disasters or financial crises with greater precision.

In conclusion, synthetic data emerges as a potent tool in machine learning, addressing the challenges posed by data scarcity, diversity, and class imbalance. It unlocks the potential for heightened accuracy, robustness, and generalization in machine learning models.

Nevertheless, a meticulous evaluation process, rigorous validation, and an unwavering commitment to ethical considerations are indispensable to ensure the responsible and effective use of synthetic data in real-world applications.

Conclusion

Synthetic data enhances machine learning models by addressing data scarcity, diversity, and class imbalance. It unlocks potential accuracy, robustness, and generalization. However, rigorous evaluation, validation, and ethical considerations are essential for responsible real-world use.

Saturn cloud - MLOps
Saturn Cloud
| August 25

ML models have grown significantly in recent years, and businesses increasingly rely on them to automate and optimize their operations. However, managing ML models can be challenging, especially as models become more complex and require more resources to train and deploy. This has led to the emergence of MLOps as a way to standardize and streamline the ML workflow.

MLOps emphasizes the need for continuous integration and continuous deployment (CI/CD) in the ML workflow, ensuring that models are updated in real-time to reflect changes in data or ML algorithms. This infrastructure is valuable in areas where accuracy, reproducibility, and reliability are critical, such as healthcare, finance, and self-driving cars.

By implementing MLOps, organizations can ensure that their ML models are continuously updated and accurate, helping to drive innovation, reduce costs, and improve efficiency.

What is MLOps?

MLOps is a methodology combining ML and DevOps practices to streamline developing, deploying, and maintaining ML models. MLOps share several key characteristics with DevOps, including:

  • CI/CD: MLOps emphasizes the need for a continuous cycle of code, data, and model updates in ML workflows. This approach requires automating as much as possible to ensure consistent and reliable results.
  • Automation: Like DevOps, MLOps stresses the importance of automation throughout the ML lifecycle. Automating critical steps in the ML workflow, such as data processing, model training, and deployment, results in a more efficient and reliable workflow.
  • Collaboration and transparency: MLOps encourages a collaborative and transparent culture of shared knowledge and expertise across teams developing and deploying ML models. This helps to ensure a streamlined process, as handoff expectations will be more standardized.
  • Infrastructure as Code (IaC): DevOps and MLOps employ an “infrastructure as code” approach, in which infrastructure is treated as code and managed through version control systems. This approach allows teams to manage infrastructure changes more efficiently and reproducibly.
  • Testing and monitoring: MLOps and DevOps emphasize the importance of testing and monitoring to ensure consistent and reliable results. In MLOps, this involves testing and monitoring the accuracy and performance of ML models over time.
  • Flexibility and agility: DevOps and MLOps emphasize flexibility and agility in response to changing business needs and requirements. This means being able to rapidly deploy and iterate on ML models to keep up with evolving business demands.

The bottom line is that ML has a lot of variability in its behavior, given that models are essentially a black box used to generate some prediction. While DevOps and MLOps share many similarities, MLOps requires a more specialized set of tools and practices to address the unique challenges posed by data-driven and computationally intensive ML workflows.

By enabling faster development time, better model performance, more reliable deployments, and enhanced efficiency, MLOps is instrumental in unlocking the full potential of harnessing ML for business intelligence and strategy.

Utilizing MLOps tools will also allow team members to focus on more important matters and businesses to save on having large dedicated teams to maintain redundant workflows.

The MLOps lifecycle

Whether creating your own MLOps infrastructure or selecting from various available MLOps platforms online, ensuring your infrastructure encompasses the four features mentioned below is critical to success. By selecting MLOps tools that address these vital aspects, you will create a continuous cycle from data scientists to deployment engineers to deploy models quickly without sacrificing quality.

 

Large language model bootcamp

 

Continuous Integration (CI)

Continuous Integration (CI) involves constantly testing and validating changes made to code and data to ensure they meet a set of defined standards. In MLOps, CI integrates new data and updates to ML models and supporting code. CI helps teams catch issues early in the development process, enabling them to collaborate more effectively and maintain high-quality ML models. Examples of CI practices in MLOps include:

  • Automated data validation checks to ensure data integrity and quality.
  • Model version control to track changes in model architecture and hyperparameters.
  • Automated unit testing of model code to catch issues before the code is merged into the production repository.

Continuous Deployment (CD)

Continuous Deployment (CD) is the automated release of software updates to production environments, such as ML models or applications. In MLOps, CD focuses on ensuring that the deployment of ML models is seamless, reliable, and consistent.

CD reduces the risk of errors during deployment and makes it easier to maintain and update ML models in response to changing business requirements. Examples of CD practices in MLOps include:

  • Automated ML pipeline with continuous deployment tools like Jenkins or CircleCI for integrating and testing model updates, then deploying them to production.
  • Containerization of ML models using technologies like Docker to achieve a consistent deployment environment, reducing potential deployment issues.
  • Implementing rolling deployments or blue-green deployments minimizes downtime and allows for an easy rollback of problematic updates.

Continuous Training (CT)

Continuous Training (CT) involves updating ML models as new data becomes available or as existing data changes over time. This essential aspect of MLOps ensures that ML models remain accurate and effective while considering the latest data and preventing model drift. Regularly training models with new data helps maintain optimal performance and achieve better business outcomes. Examples of CT practices in MLOps include:

  • Setting policies (i.e., accuracy thresholds) that trigger model retraining to maintain up-to-date accuracy.
  • Using active learning strategies to prioritize collecting valuable new data for training.
  • Employing ensemble methods to combine multiple models trained on different subsets of data, allowing for continuous model improvement and adaptation to changing data patterns.

Continuous Monitoring (CM)

Continuous Monitoring (CM) involves constantly analyzing the performance of ML models in production environments to identify potential issues, verify that models meet defined standards, and maintain overall model effectiveness. MLOps practitioners use CM to detect issues like model drift or performance degradation, which can compromise the accuracy and reliability of predictions.

By regularly monitoring the performance of their models, organizations can proactively address any problems, ensuring that their ML models remain effective and generate the desired results. Examples of CM practices in MLOps include:

  • Tracking key performance indicators (KPIs) of models in production, such as precision, recall, or other domain-specific metrics.
  • Implementing model performance monitoring dashboards for real-time visualization of model health.
  • Applying anomaly detection techniques to identify and handle concept drift, ensuring that the model can adapt to changing data patterns and maintain its accuracy over time.

How do MLOps benefit the ML lifecycle?

Managing and deploying ML models can be time-consuming and challenging, primarily due to the complexity of ML workflows, data variability, the need for iterative experimentation, and the continuous monitoring and updating of deployed models.

When the ML lifecycle is not properly streamlined with MLOps, organizations face issues such as inconsistent results due to varying data quality, slower deployment as manual processes become bottlenecks, and difficulty maintaining and updating models rapidly enough to react to changing business conditions. MLOps brings efficiency, automation, and best practices that facilitate each stage of the ML lifecycle.

Consider a scenario where a data science team without dedicated MLOps practices is developing an ML model for sales forecasting. In this scenario, the team may encounter the following challenges:

  • Data preprocessing and cleansing tasks are time-consuming due to the lack of standardized practices or automated data validation tools.
  • Difficulty in reproducibility and traceability of experiments due to inadequate versioning of model architecture, hyperparameters, and data sets.
  • Manual and inefficient deployment processes lead to delays in releasing models to production and the increased risk of errors in production environments.
  • Manual deployments can also add many failures in automatically scaling deployments across multiple servers online, affecting redundancy and uptime.
  • Inability to rapidly adjust deployed models to changes in data patterns, potentially leading to performance degradation and model drift.

There are five stages in the ML lifecycle, which are directly improved with MLOps tooling mentioned below.

Data collection and preprocessing

The first stage of the ML lifecycle involves the collection and preprocessing of data. Organizations can ensure data quality, consistency, and manageability by implementing best practices at this stage. Data versioning, automated data validation checks, and collaboration within the team lead to better accuracy and effectiveness of ML models. Examples include:

  • Data versioning to track changes in the datasets used for modeling.
  • Automated data validation checks to maintain data quality and integrity.
  • Collaboration tools within the team to share and manage data sources effectively.

Model development

MLOps helps teams follow standardized practices during the model development stage while selecting algorithms, features, and tuning hyperparameters. This reduces inefficiencies and duplicated efforts, which improves overall model performance. Implementing version control, automated experimentation tracking, and collaboration tools significantly streamline this stage of the ML Lifecycle. Examples include:

  • Implementing version control for model architecture and hyperparameters.
  • Establishing a central hub for automated experimentation tracking to reduce repeating experiments and encourage easy comparisons and discussions.
  • Visualization tools and metric tracking to foster collaboration and monitor the performance of models during development.

Model training and validation

In the training and validation stage, MLOps ensures organizations use reliable processes for training and evaluating their ML models. Organizations can effectively optimize their models’ accuracy by leveraging automation and best practices in training. MLOps practices include cross-validation, training pipeline management, and continuous integration to automatically test and validate model updates. Examples include:

  • Cross-validation techniques for better model evaluation.
  • Managing training pipelines and workflows for a more efficient and streamlined process.
  • Continuous integration workflows to automatically test and validate model updates.

Model deployment

The fourth stage is model deployment to production environments. MLOps practices in this stage help organizations deploy models more reliably and consistently, reducing the risk of errors and inconsistencies during deployment. Techniques such as containerization using Docker and automated deployment pipelines enable seamless integration of models into production environments, facilitating rollback and monitoring capabilities. Examples include:

  • Containerization using Docker for consistent deployment environments.
  • Automated deployment pipelines to handle model releases without manual intervention.
  • Rollback and monitoring capabilities for quick identification and remediation of deployment issues.

 

Model monitoring and maintenance

The fifth stage involves ongoing monitoring and maintenance of ML models in production. Utilizing MLOps principles for this stage allows organizations to evaluate and adjust models as needed consistently. Regular monitoring helps detect issues like model drift or performance degradation, which can compromise the accuracy and reliability of predictions. Key performance indicators, model performance dashboards, and alerting mechanisms ensure organizations can proactively address any problems and maintain the effectiveness of their ML models. Examples include:

  • Key performance indicators for tracking the performance of models in production.
  • Model performance dashboards for real-time visualization of the model’s health.
  • Alerting mechanisms to notify teams of sudden or gradual changes in model performance, enabling quick intervention and remediation.

MLOps tools and technologies

Adopting the right tools and technologies is crucial to implement MLOps practices and managing end-to-end ML workflows successfully. Many MLOps solutions offer many features, from data management and experimentation tracking to model deployment and monitoring. From an MLOps tool that advertises a whole ML lifecycle workflow, you should expect these features to be implemented in some manner:

  • End-to-end ML lifecycle management: All these tools are designed to support various stages of the ML lifecycle, from data preprocessing and model training to deployment and monitoring.
  • Experiment tracking and versioning: These tools provide some mechanism for tracking experiments, model versions, and pipeline runs, enabling reproducibility and comparing different approaches. Some tools might show reproducibility using other abstractions but nevertheless have some form of version control.
  • Model deployment: While the specifics differ among the tools, they all offer some model deployment functionality to help users transition their models to production environments or to provide a quick deployment endpoint to test with applications requesting model inference.
  • Integration with popular ML libraries and frameworks: These tools are compatible with popular ML libraries such as TensorFlow, PyTorch, and Scikit-learn, allowing users to leverage their existing ML tools and skills. However, the amount of support each framework has differs across tooling.
  • Scalability: Each platform provides ways to scale workflows, either horizontally, vertically, or both, enabling users to work with large data sets and train more complex models efficiently.
  • Extensibility and customization: These tools offer varying extensibility and customization, enabling users to tailor the platform to their specific needs and integrate it with other tools or services as required.
  • Collaboration and multi-user support: Each platform typically accommodates collaboration among team members, allowing them to share resources, code, data, and experimental results, fostering more effective teamwork and a shared understanding throughout the ML lifecycle.
  • Environment and dependency handling: Most of these tools include features addressing consistent and reproducible environment handling. This can involve dependency management using containers (i.e., Docker) or virtual environments (i.e., Conda) or providing preconfigured settings with popular data science libraries and tools pre-installed.
  • Monitoring and alerting: End-to-end MLOps tooling could also offer some form of performance monitoring, anomaly detection, or alerting functionality. This helps users maintain high-performing models, identify potential issues, and ensure their ML solutions remain reliable and efficient in production.

Although there is substantial overlap in the core functionalities provided by these tools, their unique implementations, execution methods, and focus areas set them apart. In other words, judging an MLOps tool at face value might be difficult when comparing their offering on paper. All of these tools provide a different workflow experience.

In the following sections, we’ll showcase some notable MLOps tools designed to provide a complete end-to-end MLOps experience and highlight the differences in how they approach and execute standard MLOps features.

MLFlow

MLflow has unique features and characteristics that differentiate it from other MLOps tools, making it appealing to users with specific requirements or preferences:

  • Modularity: One of MLflow’s most significant advantages is its modular architecture. It consists of independent components (Tracking, Projects, Models, and Registry) that can be used separately or in combination, enabling users to tailor the platform to their precise needs without being forced to adopt all components.
  • Language Agnostic: MLflow supports multiple programming languages, including Python, R, and Java, which makes it accessible to a wide range of users with diverse skill sets. This primarily benefits teams with members who prefer different programming languages for their ML workloads.
  • Integration with Popular Libraries: MLflow is designed to work with popular ML libraries such as TensorFlow, PyTorch, and Scikit-learn. This compatibility allows users to integrate MLflow seamlessly into their existing workflows, taking advantage of its management features without adopting an entirely new ecosystem or changing their current tools.
  • Active, Open-source Community: MLflow has a vibrant open-source community that contributes to its development and keeps the platform up-to-date with new trends and requirements in the MLOps space. This active community support ensures that MLflow remains a cutting-edge and relevant ML lifecycle management solution.

While MLflow is a versatile and modular tool for managing various aspects of the ML lifecycle, it has some limitations compared to other MLOps platforms. One notable area where MLflow falls short is its need for an integrated, built-in pipeline orchestration and execution feature, such as those provided by TFX or Kubeflow Pipelines.

While MLflow can structure and manage your pipeline steps using its tracking, projects, and model components, users may need to rely on external tools or custom scripting to coordinate complex end-to-end workflows and automate the execution of pipeline tasks.

As a result, organizations seeking more streamlined, out-of-the-box support for complex pipeline orchestration may find that MLflow’s capabilities need improvement and explore alternative platforms or integrations to address their pipeline management needs.

MLOps best practices

Establishing best practices in MLOps is crucial for organizations looking to develop, deploy, and maintain high-quality ML models that drive value and positively impact their business outcomes. By implementing the following practices, organizations can ensure that their ML projects are efficient, collaborative, and maintainable while minimizing the risk of potential issues arising from inconsistent data, outdated models, or slow and error-prone development:

 

  • Ensuring data quality and consistency: Establish robust preprocessing pipelines, use tools for automated data validation checks like Great Expectations or TensorFlow Data Validation, and implement data governance policies that define data storage, access, and processing rules. A lack of data quality control can lead to inaccurate or biased model results, causing poor decision-making and potential business losses.

 

  • Version control for data and models: Use version control systems like Git or DVC to track changes made to data and models, improving collaboration and reducing confusion among team members. For example, DVC can manage different versions of datasets and model experiments, allowing easy switching, sharing, and reproduction. With version control, teams can manage multiple iterations and reproduce past results for analysis.

 

  • Collaborative and reproducible workflows: Encourage collaboration by implementing clear documentation, code review processes, standardized data management, and collaborative tools and platforms like Jupyter Notebooks and Saturn Cloud. Supporting team members to work together efficiently and effectively helps accelerate the development of high-quality models. On the other hand, ignoring collaborative and reproducible workflows results in slower development, increased risk of errors, and hindered knowledge sharing.

 

  • Automated testing and validation: Adopt a rigorous testing strategy by integrating automated testing and validation techniques (e.g., unit tests with Pytest, integration tests) into your ML pipeline, leveraging continuous integration tools like GitHub Actions or Jenkins to test model functionality regularly.

Automated tests help identify and fix issues before deployment, ensuring a high-quality and reliable model performance in production. Skipping automated testing increases the risk of undetected problems, compromising model performance and ultimately hurting business outcomes.

  • Monitoring and alerting systems: Use tools like Amazon SageMaker Model Monitor, MLflow, or custom solutions to track key performance metrics and set up alerts to detect potential issues early. For example, configure alerts in MLflow when model drift is detected or specific performance thresholds are breached.

Not implementing monitoring and alerting systems delays the detection of problems like model drift or performance degradation, resulting in suboptimal decisions based on outdated or inaccurate model predictions, negatively affecting the overall business performance.

By adhering to these MLOps best practices, organizations can efficiently develop, deploy, and maintain ML models while minimizing potential issues and maximizing model effectiveness and overall business impact.

MLOps and data security

Data security plays a vital role in the successful implementation of MLOps. Organizations must take necessary precautions to guarantee that their data and models remain secure and protected at every stage of the ML lifecycle. Critical considerations for ensuring data security in MLOps include:

  • Model Robustness: Ensure your ML models can withstand adversarial attacks or perform reliably in noisy or unexpected conditions. For instance, you can incorporate techniques like adversarial training, which involves injecting adversarial examples into the training process to increase model resilience against malicious attacks.

Regularly evaluating model robustness helps prevent potential exploitation that could lead to incorrect predictions or system failures.

 

  • Data privacy and compliance: To safeguard sensitive data, organizations must adhere to relevant data privacy and compliance regulations, such as the General Data Protection Regulation (GDPR) or the Health Insurance Portability and Accountability Act (HIPAA). This may involve implementing robust data governance policies, anonymizing sensitive information, or utilizing techniques like data masking or pseudonymization.

 

  • Model security and integrity: Ensuring the security and integrity of ML models helps protect them from unauthorized access, tampering, or theft. Organizations can implement measures like encryption of model artifacts, secure storage, and model signing to validate authenticity, thereby minimizing the risk of compromise or manipulation by outside parties.

 

  • Secure deployment and access control: When deploying ML models to production environments, organizations must follow best practices for fast deployment. This includes identifying and fixing potential vulnerabilities, implementing secure communication channels (e.g., HTTPS or TLS), and enforcing strict access control mechanisms to restrict only model access to authorized users.

 

Organizations can prevent unauthorized access and maintain model security using role-based access control and authentication protocols like OAuth or SAML.

Involving security teams like red teams in the MLOps cycle can also significantly enhance overall system security. Red teams, for instance, can simulate adversarial attacks on models and infrastructure, helping identify vulnerabilities and weaknesses that might otherwise go unnoticed.

This proactive security approach enables organizations to address issues before they become threats, ensuring compliance with regulations and enhancing their ML solutions’ overall reliability and trustworthiness. Collaborating with dedicated security teams during the MLOps cycle fosters a robust security culture that ultimately contributes to the success of ML projects.

Embeddings are a key building block of large language models. For the unversed, large language models (LLMs) are composed of several key building blocks that enable them to efficiently process and understand natural language data.

A large language model (LLM) is a type of artificial intelligence model that is trained on a massive dataset of text. This dataset can be anything from books and articles to websites and social media posts. The LLM learns the statistical relationships between words, phrases, and sentences in the dataset, which allows it to generate text that is similar to the text it was trained on.

How is a large language model built?

LLMs are typically built using a transformer architecture. Transformers are a type of neural network that are well-suited for natural language processing tasks. They are able to learn long-range dependencies between words, which is essential for understanding the nuances of human language.

LLMs are so large that they cannot be run on a single computer. They are typically trained on clusters of computers or even on cloud computing platforms. The training process can take weeks or even months, depending on the size of the dataset and the complexity of the model.

Key building blocks of large language model

Foundation of LLM
Foundation of LLM

1. Embeddings

Embeddings are continuous vector representations of words or tokens that capture their semantic meanings in a high-dimensional space. They allow the model to convert discrete tokens into a format that can be processed by the neural network. LLMs learn embeddings during training to capture relationships between words, like synonyms or analogies.

2. Tokenization

Tokenization is the process of converting a sequence of text into individual words, subwords, or tokens that the model can understand. LLMs use subword algorithms like BPE or wordpiece to split text into smaller units that capture common and uncommon words. This approach helps to limit the model’s vocabulary size while maintaining its ability to represent any text sequence.

3. Attention

Attention mechanisms in LLMs, particularly the self-attention mechanism used in transformers, allow the model to weigh the importance of different words or phrases. By assigning different weights to the tokens in the input sequence, the model can focus on the most relevant information while ignoring less important details. This ability to selectively focus on specific parts of the input is crucial for capturing long-range dependencies and understanding the nuances of natural language.

 

 

4. Pre-training

Pre-training is the process of training an LLM on a large dataset, usually unsupervised or self-supervised, before fine-tuning it for a specific task. During pretraining, the model learns general language patterns, relationships between words, and other foundational knowledge.

The process creates a pretrained model that can be fine-tuned using a smaller dataset for specific tasks. This reduces the need for labeled data and training time while achieving good results in natural language processing tasks (NLP).

 

5. Transfer learning

Transfer learning is the technique of leveraging the knowledge gained during pretraining and applying it to a new, related task. In the context of LLMs, transfer learning involves fine-tuning a pretrained model on a smaller, task-specific dataset to achieve high performance on that task. The benefit of transfer learning is that it allows the model to benefit from the vast amount of general language knowledge learned during pretraining, reducing the need for large labeled datasets and extensive training for each new task.

Understanding embeddings

Embeddings are used to represent words as vectors of numbers, which can then be used by machine learning models to understand the meaning of text. Embeddings have evolved over time from the simplest one-hot encoding approach to more recent semantic embedding approaches.

Classic approaches to embeddings

In the early days of natural language processing (NLP), embeddings were simply one-hot encoded. Zero vector represents each word with a single one at the index that matches its position in the vocabulary.

1. One-hot encoding

One-hot encoding is the simplest approach to embedding words. It represents each word as a vector of zeros, with a single one at the index corresponding to the word’s position in the vocabulary. For example, if we have a vocabulary of 10,000 words, then the word “cat” would be represented as a vector of 10,000 zeros, with a single one at index 0.

One-hot encoding is a simple and efficient way to represent words as vectors of numbers. However, it does not take into account the context in which words are used. This can be a limitation for tasks such as text classification and sentiment analysis, where the context of a word can be important for determining its meaning.

For example, the word “cat” can have multiple meanings, such as “a small furry mammal” or “to hit someone with a closed fist.” In one-hot encoding, these two meanings would be represented by the same vector. This can make it difficult for machine learning models to learn the correct meaning of words.

2. TF-IDF

TF-IDF (term frequency-inverse document frequency) is a statistical measure that is used to quantify the importanceThe process creates a pretrained model that can be fine-tuned using a smaller dataset for specific tasks. This reduces the need for labeled data and training time while achieving good results in natural language processing tasks (NLP). of a word in a document. It is a widely used technique in natural language processing (NLP) for tasks such as text classification, information retrieval, and machine translation.

TF-IDF is calculated by multiplying the term frequency (TF) of a word in a document by its inverse document frequency (IDF). TF measures the number of times a word appears in a document, while IDF measures how rare a word is in a corpus of documents.

The TF-IDF score for a word is high when the word appears frequently in a document and when the word is rare in the corpus. This means that TF-IDF scores can be used to identify words that are important in a document, even if they do not appear very often.

 

Large language model bootcamp

Understanding TF-IDF with example

Here is an example of how TF-IDF can be used to create word embeddings. Let’s say we have a corpus of documents about cats. We can calculate the TF-IDF scores for all of the words in the corpus. The words with the highest TF-IDF scores will be the words that are most important in the corpus, such as “cat,” “dog,” “fur,” and “meow.”

We can then create a vector for each word, where each element of the vector represents the TF-IDF score for that word. The TF-IDF vector for the word “cat” would be high, while the TF-IDF vector for the word “dog” would also be high, but not as high as the TF-IDF vector for the word “cat.”

The TF-IDF word embeddings can then be used by a machine-learning model to classify documents about cats. The model would first create a vector representation of a new document. Then, it would compare the vector representation of the new document to the TF-IDF word embeddings. The document would be classified as a “cat” document if its vector representation is most similar to the TF-IDF word embeddings for “cat.”

Count-based and TF-IDF 

To address the limitations of one-hot encoding, count-based and TF-IDF techniques were developed. These techniques take into account the frequency of words in a document or corpus.

Count-based techniques simply count the number of times each word appears in a document. TF-IDF techniques take into account both the frequency of a word and its inverse document frequency.

Count-based and TF-IDF techniques are more effective than one-hot encoding at capturing the context in which words are used. However, they still do not capture the semantic meaning of words.

Capturing local context with N-grams

To capture the semantic meaning of words, n-grams can be used. N-grams are sequences of n-words. For example, a 2-gram is a sequence of two words.

N-grams can be used to create a vector representation of a word. The vector representation is based on the frequencies of the n-grams that contain the word.

N-grams are a more effective way to capture the semantic meaning of words than count-based or TF-IDF techniques. However, they still have some limitations. For example, they are not able to capture long-distance dependencies between words.

Semantic encoding techniques

Semantic encoding techniques are the most recent approach to embedding words. These techniques use neural networks to learn vector representations of words that capture their semantic meaning.

One of the most popular semantic encoding techniques is Word2Vec. Word2Vec uses a neural network to predict the surrounding words in a sentence. The network learns to associate words that are semantically similar with similar vector representations.

Semantic encoding techniques are the most effective way to capture the semantic meaning of words. They are able to capture long-distance dependencies between words and they are able to learn the meaning of words even if they have never been seen before. Here are some other semantic encoding techniques:

1. ELMo: Embeddings from language models

ELMo is a type of word embedding that incorporates both word-level characteristics and contextual semantics. It is created by taking the outputs of all layers of a deep bidirectional language model (bi-LSTM) and combining them in a weighted fashion. This allows ELMo to capture the meaning of a word in its context, as well as its own inherent properties.

The intuition behind ELMo is that the higher layers of the bi-LSTM capture context, while the lower layers capture syntax. This is supported by empirical results, which show that ELMo outperforms other word embeddings on tasks such as POS tagging and word sense disambiguation.

ELMo is trained to predict the next word in a sequence of words, a task called language modeling. This means that it has a good understanding of the relationships between words. When assigning an embedding to a word, ELMo takes into account the words that surround it in the sentence. This allows it to generate different embeddings for the same word depending on its context.

Understanding ELMo with example

For example, the word “play” can have multiple meanings, such as “to perform” or “a game.” In standard word embeddings, each instance of the word “play” would have the same representation. However, ELMo can distinguish between these different meanings by taking into account the context in which the word appears. In the sentence “The Broadway play premiered yesterday,” for example, ELMo would assign the word “play” an embedding that reflects its meaning as a theater production.

ELMo has been shown to be effective for a variety of natural language processing tasks, including sentiment analysis, question answering, and machine translation. It is a powerful tool that can be used to improve the performance of NLP models.

2. GloVe

GloVe is a statistical method for learning word embeddings from a corpus of text. GloVe is similar to Word2Vec, but it uses a different approach to learning the vector representations of words.

How GloVe works

GloVe works by creating a co-occurrence matrix. The co-occurrence matrix is a table that shows how often two words appear together in a corpus of text. For example, the co-occurrence matrix for the words “cat” and “dog” would show how often the words “cat” and “dog” appear together in a corpus of text.

GloVe then uses a machine learning algorithm to learn the vector representations of words from the co-occurrence matrix. The machine learning algorithm learns to associate words that appear together frequently with similar vector representations.

3. Word2Vec

Word2Vec is a semantic encoding technique that is used to learn vector representations of words. Word vectors represent word meaning and can enhance machine learning models for tasks like text classification, sentiment analysis, and machine translation.

Word2Vec works by training a neural network on a corpus of text. The neural network is trained to predict the surrounding words in a sentence. The network learns to associate words that are semantically similar with similar vector representations.

There are two main variants of Word2Vec:

  • Continuous Bag-of-Words (CBOW): The CBOW model predicts the surrounding words in a sentence based on the current word. For example, the model might be trained to predict the words “the” and “dog” given the word “cat”.
  • Skip-gram: The skip-gram model predicts the current word based on the surrounding words in a sentence. For example, the model might be trained to predict the word “cat” given the words “the” and “dog”.

Word2Vec has been shown to be effective for a variety of tasks, including:

  • Text classification: Word2Vec can be used to train a classifier to classify text into different categories, such as news articles, product reviews, and social media posts.
  • Sentiment analysis: Word2Vec can be used to train a classifier to determine the sentiment of text, such as whether it is positive, negative, or neutral.
  • Machine translation: Word2Vec can be used to train a machine translation model to translate text from one language to another.

 

 

 

 

GloVe Word2Vec ELMo
Accuracy More accurate Less accurate More accurate
Training time Faster to train Slower to train Slower to train
Scalability More scalable Less scalable Less scalable
Ability to capture long-distance dependencies Not as good at capturing long-distance dependencies Better at capturing long-distance dependencies Best at capturing long-distance dependencies

 

Word2Vec vs Dense word embeddings

Word2Vec is a neural network model that learns to represent words as vectors of numbers. Word2Vec is trained on a large corpus of text, and it learns to predict the surrounding words in a sentence.

Word2Vec can be used to create dense word embeddings. Dense word embeddings are vectors that have a fixed size, regardless of the size of the vocabulary. This makes them easy to use with machine learning models.

Dense word embeddings have been shown to be effective in a variety of NLP tasks, such as text classification, sentiment analysis, and machine translation.

Conclusion

Semantic encoding techniques are the most recent approach to embedding words and are the most effective way to capture their semantic meaning. They are able to capture long-distance dependencies between words and they are able to learn the meaning of words even if they have never been seen before.

Safe to say, embeddings are a powerful tool that can be used to improve the performance of machine learning models for a variety of tasks, such as text classification, sentiment analysis, and machine translation. As research in NLP continues to evolve, we can expect to see even more sophisticated embeddings that can capture even more of the nuances of human language.

5 essential machine learning practices
5 essential machine learning practices

Join us as we explore these key machine learning practices and uncover the secrets to optimizing machine-learning models for revolutionary advancements in diverse domains.

1. Choose the right algorithm

When choosing an algorithm, it is important to consider the following factors:

  • The type of problem you are trying to solve. Some algorithms are better suited for classification tasks, while others are better suited for regression tasks.
  • The amount of data you have. Some algorithms require a lot of data to train, while others can be trained with less data.
  • The desired accuracy. Some algorithms are more accurate than others
  • The computational resources you have available. Some algorithms are more computationally expensive than others.

Once you have considered these factors, you can start to narrow down your choices of algorithms. You can then read more about each algorithm and experiment with different algorithms to see which one works best for your problem.

2. Get enough data

Machine learning models are only as good as the data they are trained on. If you don’t have enough data, your models will not be able to learn effectively. It is important to collect as much data as possible that is relevant to your problem. The more data you have, the better your models will be.

There are a number of different ways to collect data for machine learning projects. Some common techniques include:

  1. Web scraping: Web scraping is the process of extracting data from websites. This can be done using a variety of tools and techniques.
  2. Social media: Social media platforms can be a great source of data for machine learning projects. This data can be used to train models for tasks such as sentiment analysis and topic modeling.
  3. Sensor data: Sensor data can be used to train models for tasks such as object detection and anomaly detection. This data can be collected from a variety of sources, such as smartphones, wearable devices, and traffic cameras.

3. Clean your data

Even if you have a lot of data, it is important to make sure that it is clean. This means removing any errors or outliers from your data. If your data is dirty, it will make it difficult for your models to learn effectively. There are a number of different ways to clean your data. Some common techniques include:

  • Identifying and removing errors: This can be done by looking for data that is missing, incorrect, or inconsistent.
  • Identifying and removing outliers: Outliers are data points that are significantly different from the rest of the data. They can be removed by identifying them and then removing them from the dataset.
  • Imputing missing values: Missing values can be imputed by filling them in with the mean, median, or mode of the other values in the column.
  • Transforming categorical data: Categorical data can be transformed into numerical data by using a process called one-hot encoding.

Once you have cleaned your data, you can then proceed to train your machine learning models.

4. Evaluate your models

Once you have trained your models, it is important to evaluate their performance. This can be done by using a holdout set of data that was not used to train the models. The holdout set can be used to measure the accuracy, precision, and recall of the models.

  1. Accuracy: Accuracy is the percentage of data points that are correctly classified by the model.
  2. Precision: Precision is the percentage of data points that are classified as positive that are actually positive.
  3. Recall: Recall is the percentage of positive data points that are correctly classified as positive.

The ideal model would have high accuracy, precision, and recall. However, in practice, it is often necessary to trade-off between these three metrics. For example, a model with high accuracy may have low precision or recall.

Once you have evaluated your models, you can then choose the model that has the best performance. You can then deploy the model to production and use it to make predictions.

5. Deploy your models

Once you are satisfied with the performance of your models, it is time to deploy them. This means making them available to users so that they can use them to make predictions. There are many different ways to deploy machine learning models, such as through a web service or a mobile app.

Deploying your machine learning models is considered a good practice because it enables the practical utilization of your models by making them accessible to users. Also, it has the potential to reach a broader audience, maximizing its impact.

By making your models accessible, you enable a wider range of users to benefit from the predictive capabilities of machine learning, driving decision-making processes and generating valuable outcomes.

Popular machine-learning algorithms

Here are some of the most popular machine-learning algorithms:

  1. Decision trees: Decision trees are a simple but effective algorithm for classification tasks. They work by dividing the data into smaller and smaller groups until each group can be classified with a high degree of accuracy.
  2. Linear regression: Linear regression is a simple but effective algorithm for regression tasks. It works by finding a line that best fits the data.
  3. Support vector machines: Support vector machines are a more complex algorithm that can be used for both classification and regression tasks. They work by finding a hyperplane that separates the data into two groups.
  4. Neural networks: Neural networks are powerful but complex algorithms that can be used for a variety of tasks, including classification, regression, and natural language processing.

It is important to note that there are no single “best” machine learning practices or algorithms. The best algorithm for a particular problem will depend on the specific factors of that problem.

In a nutshell

Machine learning practices are essential for accurate and reliable results. Choose the right algorithm, gather quality data, clean and preprocess it, evaluate model performance, and deploy it effectively. These practices optimize algorithm selection, data quality, accuracy, decision-making, and practical utilization. By following these practices, you improve accuracy and solve real-world problems.

Machine learning algorithms require the use of various parameters that govern the learning process. These parameters are called hyperparameters, and their optimal values are often unknown a priori. Hyperparameter tuning is the process of selecting the best values of these parameters to improve the performance of a model. In this article, we will explore the basics of hyperparameter tuning and the popular strategies used to accomplish it.  

Understanding hyperparameters 

In machine learning, a model has two types of parameters: Hyperparameters and learned parameters. The learned parameters are updated during the training process, while the hyperparameters are set before the training begins.

Hyperparameters control the model’s behavior, and their values are usually set based on domain knowledge or heuristics. Examples of hyperparameters include learning rate, regularization coefficient, batch size, and the number of hidden layers.

Learn about top 10 machine learning demos in detail 

Why is hyperparameter tuning important? 

The values of hyperparameters significantly affect the performance of a model. Suboptimal values can result in poor performance or overfitting, while optimal values can lead to better generalization and improved accuracy. In summary, hyperparameter tuning is crucial to maximizing the performance of a model.

Strategies for hyperparameter tuning 

There are different strategies used for hyperparameter tuning, and some of the most popular ones are grid search and randomized search. 

Grid search: This strategy evaluates a range of hyperparameter values by exhaustively searching through all possible combinations of parameter values in a grid. The best combination is selected based on the model’s performance metrics.  

Randomized Search: This strategy evaluates a random set of hyperparameter values within a given range. This approach can be faster than grid search and can still produce good results. 

H3: general hyperparameter tuning strategy 

To effectively tune hyperparameters, it is crucial to follow a general strategy. According to, a general hyperparameter tuning strategy consists of three phases: 

  • Preprocessing and feature engineering 
  • Initial modeling and hyperparameter selection 
  • Refining hyperparameters 


Preprocessing and feature engineering
 

The first phase involves preprocessing and feature engineering. This includes data cleaning, data normalization, and feature selection. In this phase, hyperparameters that affect the preprocessing and feature engineering steps are set, such as the number of features to be selected. 

Initial modeling and hyperparameter selection 

The second phase involves initializing the model and selecting a range of hyperparameter values to test. This includes setting the model type and other model-specific hyperparameters, such as the learning rate or the number of hidden layers.  

Refining hyperparameters 

In the final phase, the hyperparameters are fine-tuned by adjusting their values based on the model’s performance metrics. This can be done using gridsearchcv, randomizedsearchcv, or other strategies. 

Most common questions asked about hyperparameters 

Q: Can hyperparameters be learned during training? 

A: No, hyperparameters are set before the training begins and are not updated during the training process.   

Q: Why is it necessary to set the hyperparameters? 

A: Hyperparameters control the learning process of a model, and their values can significantly affect its performance. Setting the hyperparameters helps to improve the model’s accuracy and prevent overfitting. 

Methods for hyperparameter tuning in machine learning

Hyperparameter tuning is an essential step in machine learning to fine-tune models and improve their performance. Several methods are used to tune hyperparameters, including grid search, random search, and bayesian optimization. Here’s a brief overview of each method:  

Ready to take your machine learning skills to the next level? Click on the video to learn more about building robust models.

1. Grid search:

Grid search is a commonly used method for hyperparameter tuning. In this method, a predefined set of hyperparameters is defined, and each combination of hyperparameters is tried to find the best set of values.

Grid search is suitable for small and quick searches of hyperparameter values that are known to perform well generally. However, it may not be an efficient method when the search space is large. 

2. Random search:

Unlike grid search, in a random search, only a part of the parameter values are tried out. In this method, the parameter values are sampled from a given list or specified distribution, and the number of parameter settings that are sampled is given by n_iter.

Random search is appropriate for discovering new hyperparameter values or new combinations of hyperparameters, often resulting in better performance, although it may take more time to complete. 

3. Bayesian optimization:

Bayesian optimization is a method for hyperparameter tuning that aims to find the best set of hyperparameters by building a probabilistic model of the objective function and then searching for the optimal values. This method is suitable when the search space is large and complex.

Bayesian optimization is based on the principle of Bayes’s theorem, which allows the algorithm to update its belief about the objective function as it evaluates more hyperparameters. This method can converge quickly and may result in better performance than grid search and random search.

Choosing the right method for hyperparameter tuning

In conclusion, hyperparameter tuning is essential in machine learning, and several methods can be used to fine-tune models. Grid search is a simple and efficient method for small search spaces, while the random search can be used for discovering new hyperparameter values.

Bayesian optimization is a powerful method for complex and large search spaces that can result in better performance by building a probabilistic model of the objective function. It’s choosing the right method based on the problem at hand is essential.

Imbalanced data is a common problem in machine learning, where one class has a significantly higher number of observations than the other. This can lead to biased models and poor performance on the minority class. In this blog, we will discuss techniques for handling imbalanced data and improving model performance.   

Understanding imbalanced data 

Imbalanced data refers to datasets where the distribution of class labels is not equal, with one class having a significantly higher number of observations than the other. This can be a problem for machine learning algorithms, as they can be biased towards the majority class and perform poorly on the minority class. 

Techniques for handling imbalanced data

Dealing with imbalanced data is a common problem in data science, where the target class has an uneven distribution of observations. In classification problems, this can lead to models that are biased toward the majority class, resulting in poor performance of the minority class. To handle imbalanced data, various techniques can be employed. 

How to handle imbalanced data
How to handle imbalanced data – Data Science Dojo

 1. Resampling techniques

Resampling techniques involve modifying the original dataset to balance the class distribution. This can be done by either oversampling the minority class or undersampling the majority class. 

Oversampling techniques include random oversampling, synthetic minority over-sampling technique (SMOTE), and adaptive synthetic (ADASYN). Undersampling techniques include random undersampling, nearmiss, and tomek links. 

An example of a resampling technique is bootstrap resampling, where you generate new data samples by randomly selecting observations from the original dataset with replacements. These new samples are then used to estimate the variability of a statistic or to construct a confidence interval.  

For instance, if you have a dataset of 100 observations, you can draw 100 new samples of size 100 with replacement from the original dataset. Then, you can compute the mean of each new sample, resulting in 100 new mean values. By examining the distribution of these means, you can estimate the standard error of the mean or the confidence interval of the population mean. 

2. Data augmentation

Data augmentation involves creating additional data points by modifying existing data. This can be done by applying various transformations such as rotations, translations, and flips to the existing data.

Read about top statistical techniques in this blog  

3. Synthetic minority over-sampling technique (SMOTE)

SMOTE is a type of oversampling technique that involves creating synthetic examples of the minority class by interpolating between existing minority class examples.

4. Ensemble techniques

Ensemble techniques involve combining multiple models to improve performance. This can be done by using techniques such as bagging, boosting, and stacking.

5. One-class classification

One-class classification involves training a model on only one class and then using it to identify data points that do not belong to that class. This can be useful for identifying anomalies and outliers in the data.

6. Cost-sensitive learning

Cost-sensitive learning involves adjusting the cost of misclassifying data points to account for the class imbalance. This can be done by assigning a higher cost to misclassifying the minority class, which encourages the model to prioritize correctly classifying the minority class.

7. Evaluation metrics for imbalanced data

Evaluation metrics such as precision, recall, and F1 score can be used to evaluate the performance of models on imbalanced data. Additionally, metrics such as the area under the receiver operating characteristic curve (AUC-ROC) and the area under the precision-recall curve (AUC-PR) can also be used. 

Choosing the best technique for handling imbalanced data 

After discussing techniques for handling imbalanced data, we learned several approaches that can be used to address the issue. The most common techniques include undersampling, oversampling, and feature selection. 

Undersampling involves reducing the size of the majority class to match that of the minority class, while oversampling involves creating new instances of the minority class to balance the data. Feature selection is the process of selecting only the most relevant features to reduce the noise in the data.  

In conclusion, it is recommended to use both undersampling and oversampling techniques to balance the data, with oversampling being the most effective. However, the choice of technique will ultimately depend on the specific characteristics of the dataset and the problem at hand.

Emerging AI and machine learning trends

Data security and regulations 

In today’s economy, data is the main commodity. To rephrase, intellectual capital is the most precious asset that businesses must safeguard. The quantity of data they manage, as well as the hazards connected with it, is only going to expand after the emergence of AI and ML. Large volumes of private information are backed up and archived by many companies nowadays, which poses a growing privacy danger. Don Evans, CEO of Crewe Foundation   

data_security

The future currency is data. In other words, it’s the most priceless resource that businesses must safeguard. The amount of data they handle, and the hazards attached to it will only grow when AI and ML are brought into the mix. Today’s businesses, for instance, back up and store enormous volumes of sensitive customer data, which is expected to increase privacy risks by 2023.
 

Overlap of AI and IoT 

There is a blurring of boundaries between AI and the Internet of Things. While each technology has merits of its own, only when they are combined can they offer novel possibilities? Smart voice assistants like Alexa and Siri only exist because AI and the Internet of Things have come together. Why, therefore, do these two technologies complement one another so well?

The Internet of Things (IoT) is the digital nervous system, while Artificial Intelligence (AI) is the decision-making brain. AI’s speed at analyzing large amounts of data for patterns and trends improves the intelligence of IoT devices. As of now, just 10% of commercial IoT initiatives make use of AI, but that number is expected to climb to 80% by 2023. Josh Thill, Founder of Thrive Engine 

AI ethics: Understanding biased AI and associated ethical dilemmas 
AI ethics: Understanding biased AI and associated ethical dilemmas

Why then do these two technologies complement one other so well? IoT and AI can be compared to the brain and nervous system of the digital world, respectively. IoT systems have become more sophisticated thanks to AI’s capacity to quickly extract insights from data. Software developers and embedded engineers now have another reason to include AI/ML skills in their resumes because of this development in AI and machine learning. 

 

Augmented Intelligence   

The growth of augmented intelligence should be a relieving trend for individuals who may still be concerned about AI stealing their jobs. It combines the greatest traits of both people and technology, offering businesses the ability to raise the productivity and effectiveness of their staff.

40% of infrastructure and operations teams in big businesses will employ AI-enhanced automation by 2023, increasing efficiency. Naturally, for best results, their staff should be knowledgeable in data science and analytics or have access to training in the newest AI and ML technologies. 

Moving on from the concept of Artificial Intelligence to Augmented Intelligence, where decisions models are blended artificial and human intelligence, where AI finds, summarizes, and collates information from across the information landscape – for example, company’s internal data sources. This information is presented to the human operator, who can make a human decision based on that information. This trend is supported by recent breakthroughs in Natural Language Processing (NLP) and Natural Language Understanding (NLU). Kuba Misiorny, CTO of Untrite Ltd
 

Transparency 

Despite being increasingly commonplace, there are trust problems with AI. Businesses will want to utilize AI systems more frequently, and they will want to do so with greater assurance. Nobody wants to put their trust in a system they don’t fully comprehend.

As a result, in 2023 there will be a stronger push for the deployment of AI in a visible and specified manner. Businesses will work to grasp how AI models and algorithms function, but AI/ML software providers will need to make complex ML solutions easier for consumers to understand.

The importance of experts who work in the trenches of programming and algorithm development will increase as transparency becomes a hot topic in the AI world. 

Composite AI 

Composite AI is a new approach that generates deeper insights from any content and data by fusing different AI technologies. Knowledge graphs are much more symbolic, explicitly modeling domain knowledge and, when combined with the statistical approach of ML, create a compelling proposition. Composite AI expands the quality and scope of AI applications and, as a result, is more accurate, faster, transparent, and understandable, and delivers better results to the user. Dorian Selz, CEO of Squirro

It’s a major advance in the evolution of AI and marrying content with context and intent allows organizations to get enormous value from the ever-increasing volume of enterprise data. Composite AI will be a major trend for 2023 and beyond. 

Continuous focus on healthcare

There has been concern that AI will eventually replace humans in the workforce ever since the concept was first proposed in the 1950s. Throughout 2018, a deep learning algorithm was constructed that demonstrated accurate diagnosis utilizing a dataset consisting of more than 50,000 normal chest pictures and 7,000 scans that revealed active Tuberculosis. Since then, I believe that the healthcare business has mostly made use of Machine Learning (ML) and Deep Learning applications of artificial intelligence. Marie Ysais, Founder of Ysais Digital Marketing

Learn more about the role of AI in healthcare:

AI in healthcare has improved patient care

 

Pathology-assisted diagnosis, intelligent imaging, medical robotics, and the analysis of patient information are just a few of the many applications of artificial intelligence in the healthcare industry. Leading stakeholders in the healthcare industry have been presented with advancements and machine-learning models from some of the world’s largest technology companies. Next year, 2023, will be an important year to observe developments in the field of artificial intelligence.
 

Algorithmic decision-making 

Advanced algorithms are taking on the skills of human doctors, and while AI may increase productivity in the medical world, nothing can take the place of actual doctors. Even in robotic surgery, the whole procedure is physician-guided. AI is a good supplement to physician-led health care. The future of medicine will be high-tech with a human touch.  

 

No-code tools   

The low-code/No Code ML revolution accelerates creating a new breed of Citizen AI. These tools fuel mainstream ML adoption in businesses that were previously left out of the first ML wave (mostly taken advantage of by BigTech and other large institutions with even larger resources). Maya Mikhailov Founder of Savvi AI 

Low-code intelligent automation platforms allow business users to build sophisticated solutions that automate tasks, orchestrate workflows, and automate decisions. They offer easy-to-use, intuitive drag-and-drop interfaces, all without the need to write a line of code. As a result, low-code intelligent automation platforms are popular with tech-savvy business users, who no longer need to rely on professional programmers to design their business solutions. 

 

Cognitive analytics 

Cognitive analytics is another emerging trend that will continue to grow in popularity over the next few years. The ability for computers to analyze data in a way that humans can understand is something that has been around for a while now but is only recently becoming available in applications such as Google Analytics or Siri—and it’ll only get better from here! 

 

Virtual assistants 

Virtual assistants are another area where NLP is being used to enable more natural human-computer interaction. Virtual assistants like Amazon Alexa and Google Assistant are becoming increasingly common in homes and businesses. In 2023, we can expect to see them become even more widespread as they evolve and improve. Idrees Shafiq-Marketing Research Analyst at Astrill

virtual reality

Virtual assistants are becoming increasingly popular, thanks to their convenience and ability to provide personalized assistance. In 2023, we can expect to see even more people using virtual assistants, as they become more sophisticated and can handle a wider range of tasks. Additionally, we can expect to see businesses increasingly using virtual assistants for customer service, sales, and marketing tasks.
 

Information security (InfoSec)

The methods and devices used by companies to safeguard information fall under the category of information security. It comprises settings for policies that are essentially designed to stop the act of stopping unlawful access to, use of, disclosure of, disruption of, modification of, an inspection of, recording of, or data destruction.

With AI models that cover a broad range of sectors, from network and security architecture to testing and auditing, AI prediction claims that it is a developing and expanding field. To safeguard sensitive data from potential cyberattacks, information security procedures are constructed on the three fundamental goals of confidentiality, integrity, and availability, or the CIA. Daniel Foley, Founder of Daniel Foley SEO 

 

Wearable devices 

The continued growth of the wearable market. Wearable devices, such as fitness trackers and smartwatches, are becoming more popular as they become more affordable and functional. These devices collect data that can be used by AI applications to provide insights into user behavior. Oberon, Founder, and CEO of Very Informed 

 

Process discovery

It can be characterized as a combination of tools and methods with heavy reliance on artificial intelligence (AI) and machine learning to assess the performance of persons participating in the business process. In comparison to prior versions of process mining, these goes further in figuring out what occurs when individuals interact in different ways with various objects to produce business process events.

The methodologies and AI models vary widely, from clicks of the mouse for specific reasons to opening files, papers, web pages, and so forth. All of this necessitates various information transformation techniques. The automated procedure using AI models is intended to increase the effectiveness of commercial procedures. Salim Benadel, Director at Storm Internet

 

Robotic Process Automation, or RPA. 

An emerging tech trend that will start becoming more popular is Robotic Process Automation or RPA. It is like AI and machine learning, and it is used for specific types of job automation. Right now, it is primarily used for things like data handling, dealing with transactions, processing/interpreting job applications, and automated email responses. It makes many businesses processes much faster and more efficient, and as time goes on, increased processes will be taken over by RPA. Maria Britton, CEO of Trade Show Labs 

Robotic process automation is an application of artificial intelligence that configures a robot (software application) to interpret, communicate and analyze data. This form of artificial intelligence helps to automate partially or fully manual operations that are repetitive and rule based. Percy Grunwald, Co-Founder of Hosting Data 

 

Generative AI 

Most individuals say AI is good for automating normal, repetitive work. AI technologies and applications are being developed to replicate creativity, one of the most distinctive human skills. Generative AI algorithms leverage existing data (video, photos, sounds, or computer code) to create new, non-digital material.

Deepfake films and the Metaphysic act on America’s Got Talent have popularized the technology. In 2023, organizations will increasingly employ it to manufacture fake data. Synthetic audio and video data can eliminate the need to record film and speech on video. Simply write what you want the audience to see and hear, and the AI creates it. Leonidas Sfyris 

With the rise of personalization in video games, new content has become increasingly important. Companies are not able to hire enough artists to constantly create new themes for all the different characters so the ability to put in a concept like a cowboy and then the art assets created for all their characters becomes a powerful tool. 

 

Observability in practice

By delving deeply into contemporary networked systems, Applied Observability facilitates the discovery and resolution of issues more quickly and automatically. Applied observability is a method for keeping tabs on the health of a sophisticated structure by collecting and analyzing data in real time to identify and fix problems as soon as they arise.

Utilize observability for application monitoring and debugging. Telemetry data including logs, metrics, traces, and dependencies are collected by Observability. The data is then correlated in actuality to provide responders with full context for the incidents they’re called to. Automation, machine learning, and artificial intelligence (AIOps) might be used to eliminate the need for human interaction in problem-solving. Jason Wise, Chief Editor at Earthweb 

 

Natural Language Processing 

As more and more business processes are conducted through digital channels, including social media, e-commerce, customer service, and chatbots, NLP will become increasingly important for understanding user intent and producing the appropriate response.

Natural Language Processing – Tasks and techniques

 

In 2023, we can expect to see increased use of Natural Language Processing (NLP) for communication and data analysis. NLP has already seen widespread adoption in customer service chatbots, but it may also be utilized for data analysis, such as extracting information from unstructured texts or analyzing sentiment in large sets of customer reviews. Additionally, deep learning algorithms have already shown great promise in areas such as image recognition and autonomous vehicles.

In the coming years, we can expect to see these algorithms applied to various industries such as healthcare for medical imaging analysis and finance for stock market prediction. Lastly, the integration of AI tools into various industries will continue to bring about both exciting opportunities and ethical considerations. Nicole Pav, AI Expert.

Hundred page machine learning book

If we have to teach machine learning to someone in juts few weeks, it is a lot better not to bother starting from scratch, instead hand over this book to the learners, because no doubt Andriy Burkov does a better job than we could do to quickly teach this vast subject in a limited time.

The book has a litany of rave reviews from some of the biggest names in tech, with scores more five-star reviews to boot, and you can see why. Burkov keeps his lessons concise and as easy to understand as possible given the subject matter, but still drills down into the details where necessary. Overall, the book excels at linking together complicated and sometimes seemingly unrelated concepts into a coherent whole. Peter, CEO and founder – Lantech

The book is very well organized, giving the reader an introduction and discussion on the mathematical notation used, a well written chapter that discusses several quite common algorithms, talks about best practices (like feature engineering, breaking up the data into multiple sets, and tuning the model’s hyperparameters), digs deeper into supervised learning, discusses unsupervised learning, and gives you a taste of a variety of other related topics.

This is a well-rounded book, far more so than most books I’ve read on machine learning or artificial intelligence. After reading through this, you will feel like you can competently discuss the subject, read one of the simpler machine learning research papers, and not be totally lost on the mathematics involved. The language used is concise and reads very well, showing very tight editing

5. Hands-On Machine Learning with Scikit-Learn, Keras, and TensorFlow by Aurélien Géron

It’s good for new programmers without over-simplifying. I’d recommend it for really getting into practice exercises. It’s a book you need to take your time with, but you’ll learn a lot from it. One thing observed by the learners of this book as a con is that the quality of the print varies, but the quality of its content makes it more than worth it. Chris Martinez – Founder of Idiomatic

6. Machine Learning for Absolute Beginners by Oliver Theobald

Machine learning for beginners
Machine learning for beginners by Oliver Theobald

Machine Learning is easy only when you have the right teacher and an appropriate reference book. Most of us fail to understand the importance of simple concepts that help us understand complex ones. Therefore, I recommend using Oliver Theobald’s *Machine Learning for Absolute Beginners *as the base reference book. Layla Acharya – Owner at Edwize

This book uses simple language to explain to the reader and teaches Machine learning from the scratch. Although non-technical people will find this book more relatable, people wanting to make a career in the machine learning field can benefit equally. It also has good references that can help a person who wants to learn like an expert.

7. Deep Learning for Coders with Fastai and PyTorch: AI Applications Without a PhD by Jeremy Howard and Sylvain Gugger

Deep learning for coders
Deep learning for coders with fastai and PyTorch

This book is very well-rated, and it’s helped me a lot in understanding the basics of deep learning.

The main reason readers suggest this book is because it’s very accessible and easy to follow. As the authors themselves say, you don’t need a PhD to understand and use the concepts in the book, and it follows a top-down approach (starting with the applications and working backwards to the theory). So, you’ll first have fun building cool applications and then gradually learn the underlying theory as you go. Ed Shway – Owner & Writer at ByteXD.com

Fast AI have kept updating their courses and library, so you might want to check out their website (https://www.fast.ai/) for the latest and greatest Just this July they released a latest version of the course that the book is associated with (https://course.fast.ai/).

Furthermore, the book also comes in a free online version https://github.com/fastai/fastbook. Since the *Fast AI team put all this effort and made every resource available for free, you can be sure they’re in it for the love of the game and to help the community*, rather than to make a quick buck. So, this book is definitely worth your time.

The first practical applications it teaches you is in computer vision – you’ll build an image classifier, which you can use to tell apart different
kinds of images. For example, you can use it to distinguish between different kinds of animals. It will be very easy to follow along and build
this classifier yourself.

 

8. Bayesian Reasoning and Machine Learning by David Barber

Bayesian reasoning and machine learning book
Bayesian reasoning and machine learning book

It’s a real must-have for beginners interested in deepening their knowledge of machine learning in an engaging way. The book covers topics such as dynamic and probabilistic models, approximate interference, graphical models, Naive Bayes algorithms, and more. What makes it worth checking out is the fact that the book is full of examples and exercises, which makes it a hands-on guide full of useful practice rather than dry theoretical frameworks. Marcin Gwizdala – Chief Technical Officer – Tidio

For relative beginners, Bayesian techniques began in the 1700s to model how a degree of belief should be modified to account for new evidence. The techniques and formulas were largely discounted and ignored until the modern era of computing, pattern recognition and AI, now machine learning.

The formula answers how the probabilities of two events are related when represented inversely, and more broadly, gives a precise mathematical model for the inference process itself (under uncertainty), where deductive reasoning and logic becomes a subset (under certainty, or when values can resolve to 0/1 or true/false, yes/no etc. In “odds” terms (useful in many fields including optimal expected utility functions in decision theory), posterior odds = prior odds * the Bayes Factor.

9. Deep Learning with PyTorch: Build, train, and tune neural networks using Python tools by Eli Stevens, Luca Antiga, Thomas Viehmann

Deep learning with Pytorch
Deep learning with Pytorch

This book provides a good and fairly complete description of the basic principles and abstractions of one of the most popular frameworks for
Machine Learning – PyTorch.

It’s great that this book is written by the creator and key contributors of PyTorch, unlike many books that claim to be a definitive treatise, it is not overloaded with non-essential details, the emphasis is on making the book practical. The book gives a reader a deep understanding of the framework and methods for building and training models on it (with advanced best practices) describing what is under the hood. Vitalii Kudelia, TUTU – Machine Learning Scientist

There is an example of solving a real-world problem in this book, it analyzes the problem of searching for malignant tumors on a computer
diagram with an analysis of approaches, possible errors, options for improvements, and provides code examples.

It also includes options for translating the model into production, using the models in other programming languages, and on mobile devices.
As a result, the book is highly useful for understanding and mastering the framework. Mastering PyTorch helps not only in computer vision, but also in other areas of deep learning, such as, for example, natural language processing.

Most people have heard the terms “data science” and “AI” at least once in their lives. Indeed, both of these are extremely important in the modern world, as they are technologies that help us run quite a few of our industries. 

But even though data science and Artificial Intelligence are somewhat related to one another, they are still very different. There are things they have in common, which is why they are often used together, but it is crucial to understand their differences as well. 

What is Data Science? 

As the name suggests, data science is a field that involves studying and processing large quantities of data using a variety of technologies and techniques to detect patterns, make conclusions about the data, and aid in the decision-making process. Essentially, it is an intersection of statistics and computer science largely used in business and different industries. 

Artificial Intelligence (AI) vs Data science vs Machine learning
Artificial Intelligence vs Data science vs Machine learning – Image source

The standard data science lifecycle includes capturing data and then maintaining, processing, and analyzing it before finally communicating conclusions about it through reporting. This makes data science extremely important for analysis, prediction, decision-making, problem-solving, and many other purposes. 

 

 

What is Artificial Intelligence? 

Artificial Intelligence is the field that involves the simulation of human intelligence and the processes within it by machines and computer systems. Today, it is used in a wide variety of industries and allows our society to function as it currently does by using different AI-based technologies. 

Some of the most common examples in action include machine learning, speech recognition, and search engine algorithms. While AI technologies are rapidly developing, there is still a lot of room for their growth and improvement. For instance, there is no powerful enough content generation tool that can write texts that are as good as those written by humans. Therefore, it is always preferred to hire an experienced writer to maintain the quality of work.  

What is Machine Learning? 

As mentioned above, machine learning is a type of AI-based technology that uses data to “learn” and improve specific tasks that a machine or system is programmed to perform. Though machine learning is seen as a part of the greater field of AI, its use of data puts it firmly at the intersection of data science and AI. 

Similarities between Data Science and AI 

By far the most important point of connection between data science and Artificial Intelligence is data. Without data, neither of the two fields would exist, and the technologies within them would not be used so widely in all kinds of industries. In many cases, data scientists and AI specialists work together to create new technologies, improve old ones, and find better ways to handle data. 

As explained earlier, there is a lot of room for improvement when it comes to AI technologies. The same can be somewhat said about data science. That’s one of the reasons businesses still hire professionals to accomplish certain tasks, like custom writing requirements, design requirements, and other administrative work.  

Differences between Data Science and AI 

There are quite a few differences between both. These include: 

  • Purpose – It aims to analyze data to make conclusions, predictions, and decisions. Artificial Intelligence aims to enable computers and programs to perform complex processes in a similar way to how humans do. 
  • Scope – This includes a variety of data-related operations such as data mining, cleansing, reporting, etc. It primarily focuses on machine learning, but there are other technologies involved too such as robotics, neural networks, etc. 
  • Application – Both are used in almost every aspect of our lives, but while data science is predominantly present in business, marketing, and advertising, AI is used in automation, transport, manufacturing, and healthcare. 

Examples of Data Science and Artificial Intelligence in use 

To give you an even better idea of what data science and Artificial Intelligence are used for, here are some of the most interesting examples of their application in practice: 

  • Analytics – Analyze customers to better understand the target audience and offer the kind of product or service that the audience is looking for. 
  • Monitoring – Monitor the social media activity of specific types of users and analyze their behavior. 
  • PredictionAnalyze the market and predict demand for specific products or services in the nearest future. 
  • Recommendation – Recommend products and services to customers based on their customer profiles, buying behavior, etc. 
  • Forecasting – Predict the weather based on a variety of factors and then use these predictions for better decision-making in the agricultural sector. 
  • Communication – Provide high-quality customer service and support with the help of chatbots. 
  • Automation – Automate processes in all kinds of industries, from retail and manufacturing to email marketing and pop-up on-site optimization. 
  • Diagnosing – Identify and predict diseases, give correct diagnoses, and personalize healthcare recommendations. 
  • Transportation – Use self-driving cars to get where you need to go. Use self-navigating maps to travel. 
  • Assistance – Get assistance from smart voice assistants that can schedule appointments, search for information online, make calls, play music, and more. 
  • Filtering – Identify spam emails and automatically get them filtered into the spam folder. 
  • Cleaning – Get your home cleaned by a smart vacuum cleaner that moves around on its own and cleans the floor for you. 
  • Editing – Check texts for plagiarism, proofread, and edit them by detecting grammatical, spelling, punctuation, and other linguistic mistakes. 

It is not always easy to tell which of these examples is about data science and which one is about Artificial Intelligence because many of these applications use both of them. This way, it becomes even clearer just how much overlap there is between these two fields and the technologies that come from them. 

What is your choice?

At the end of the day, data science and AI remain some of the most important technologies in our society and will likely help us invent more things and progress further. As a regular citizen, understanding the similarities and differences between the two will help you better understand how data science and Artificial Intelligence are used in almost all spheres of our lives.

In this blog, we will discuss the top 8 Machine Learning algorithms that will help you to receive and analyze input data to predict output values within an acceptable range

Machine learning algorithms
Top 8 machine learning algorithms explained

1. Linear Regression 

Linear regression
Linear regression – Machine learning algorithm – Data Science Dojo

Linear regression is a simple machine learning model and chances are you are already aware of it! Do you remember plotting the line y=mx+c in your introductory algebra class? This is an equation of a straight line where m is its gradient and c is the point where the line crosses the y-axis. Using this equation, you’re able to estimate the value of y for any given value of x. Similarly, linear regression involves estimating the relationship between independent variables (x) and a dependent variable(y).  

 

2. Logistic Regression 

Logistic regression

Just like linear regression, logistic regression is a machine learning model used to determine the relationship between a dependent variable and one or more independent variables. However, this model is used for classification analysis. This is because logistic regression predicts the probability of an event occurring. For a probability greater than 0.5, a value of 1 is assigned, and for less than that 0. For example, you can use logistic regression to predict whether a student will pass (1) an exam, or they will fail (0).

3. Decision Trees

Decision tree is a supervised machine learning model that repeatedly splits the data based on a question corresponding to the features. The model learns the best way to reduce randomness and drafts a decision tree that can be used to predict the category of an item based on answering a selection of questions. For example, in the case of whether it will rain today or not, the questions can be whether it is sunny, did it rain yesterday, whether it is windy, and so on.  

 

4. Random Forest 

Random forest
Random forest – Machine learning algorithm – Data Science Dojo

Random Forest is a machine learning algorithm that works similarly to a decision tree. The difference is that random forest uses multiple decision trees to make a prediction and hence decreases overfitting. The process of majority voting is carried out and the class selected by most trees is assigned to an item. For example, if two trees predict it to be 0, and one tree predicts it to be 1, then the class of 0 will be assigned to the item.  

5. K-Nearest Neighbor 

K-nearest neighbour
K-nearest neighbor – Machine learning algorithm – Data Science Dojo

K-Nearest Neighbor is another simple machine learning algorithm that classifies new cases based on the category/class of the data points nearest to the new data point. That is, if most neighbors of an unknown item belong to class 1, then we assign class 1 to this unknown item. The number of neighbors to take into consideration is the value K assigned. If k=10, we will look at the 10 nearest neighbors of this item. The nearest neighbors are determined by measuring the distance using distance measures such as Euclidean distance, and the nearest are those that have the shortest distance. 

 

6. Support Vector Machine 

Support vector machine
Support vector machine – Machine learning algorithm – Data Science Dojo

Support vector machines by dividing the data points using a hyperplane which is a straight line. The points donated by the blue diamond form one class on the left side of the plane and the points donated by the green circle represent another class on the right side of the plane. If we want to predict the class of a new point, we can simply determine it by whether it lies on the left or right side of the hyperplane and where it is within the margin. 

7. K-Means clustering 

k-means clustering
K-means clustering – Machine learning algorithm

K-means clustering is an unsupervised machine learning algorithm. That means it is used to work with data points whose class is not already known. We can use the clustering algorithm to group similar items into clusters. The number of clusters is determined by the value of K assigned. For example, you assign K=3. Three clusters are selected at random, and we adjust them until they are highly distinct from one another. Distinct clusters will have points similar to each other but these points will be distinct from points in another cluster.

8. Naïve Bayes

Naive Bayes classifier
Naive Bayes classifier – Machine learning algorithm – Data Science Dojo

Naïve Bayes is a probabilistic machine learning model based on the Bayes theorem that assumes that all the features are independent of one another. Conditional probability refers to the probability of an outcome occurring if it is given that another event has occurred. This algorithm predicts the probability that an item belongs to a particular class and is assigned the class with the highest probability.

Data Science Dojo is offering Apache Zeppelin for FREE on Azure Marketplace packaged with pre-installed interpreters and backends to make Machine Learning easier than ever. 

Introduction 

How cumbersome and tiring it is to install different tools to perform your desired ML tasks and then look after the integration and dependency issues. Already getting headaches? Worry not, because Data Science Dojo’s Apache Zeppelin instance fixes all of that. But before we delve further into it, let’s get to know some basics. 

 

What are Machine Learning Operations?  

Machine Learning is a branch of Artificial Intelligence that deals with models that produce outcomes based on some learned pre-existing data. It provides automation and reduces the workload of users. ML converges with Data Science and Engineering and that gives birth to some necessary operations to be performed to acquire the output of any task.

These operations include ETL (Extraction, Transform, Load) or ELT, drawing interactive visualizations, running queries, training and testing ML models and several other functions. 

Pro Tip: Join our 6-months instructor-led Data Science Bootcamp to master machine learning skills. 

 

Challenges for individuals 

 Wanting to explore and visualize your data but not knowing the methodology of the new tool is not only a red flag but also demands extraneous skills to be learnt to proceed with your job. Or you would have to switch among different environments to achieve your goal which is again – time-consuming, and needless to say time is of the essence for data scientists and engineers when they must deliver a task.

In this scenario, switching from one tool to another which you may know how to use or may not, is time and cost intensive. What if a data driven interactive environment having several interpreters ready to be worked with in one place is provided and you just select your favorite language and break the ice? 

 

ML Operations with Apache Zeppelin 

Apache Zeppelin is an open-source tool that equips you with a web-based notebook that can be used for data processing and querying, handling big data, training and testing models, interactive data analytics, visualization, and exploration. Vibrant designs and pictures generated can save time for users in the identification of key patterns in data and ultimately accelerates the decision-making processes.

It contains different pre-installed interpreters but also allows you to plug in your own various language backends for desirability. Apache Zeppelin supports many data sources which allow you to synthesize your data to visualize into interactive plots and charts. You can also create dynamic forms in your notebook and can share your notebook with collaborators.

Be it Netflix, Amazon, or another mega-giant, their success stands on the shoulders of experts, analysts are busy deploying machine learning through supervised, unsupervised, and reinforcement successfully. 

The tremendous amount of data being generated via computers, smartphones, and other technologies can be overwhelming, especially for those who do not know what to make of it. To make the best use of data researchers and programmers often leverage machine learning for an engaging user experience.

Many advanced techniques that are coming up every day for data scientists of all supervised, and unsupervised, reinforcement learning is leveraged often. In this article, we will briefly explain what supervised, unsupervised, and reinforcement learning is, how they are different, and the relevant uses of each by well-renowned companies.

Machine learning
                                                                                    Machine Learning techniques –  Image Source

Supervised learning

Supervised machine learning is used for making predictions from data. To be able to do that, we need to know what to predict, which is also known as the target variable. The datasets where the target label is known are called labeled datasets to teach algorithms that can properly categorize data or predict outcomes. Therefore, for supervised learning:

  • We need to know the target value
  • Targets are known in labeled datasets

Let’s look at an example: If we want to predict the prices of houses, supervised learning can help us predict that. For this, we will train the model using characteristics of the houses, such as the area (sq ft.), the number of bedrooms, amenities nearby, and other similar characteristics, but most importantly the variable that needs to be predicted – the price of the house.

A supervised machine learning algorithm can make predictions such as predicting the different prices of the house using the features mentioned earlier, predicting trends of future sales, and many more.

Sometimes this information may be easily accessible while other times, it may prove to be costly, unavailable, or difficult to obtain, which is one of the main drawbacks of supervised learning.

Saniye Alabeyi, Senior Director Analyst at Garnet calls Supervised learning the backbone of today’s economy, stating:

“Through 2022, supervised learning will remain the type of ML utilized most by enterprise IT leaders” (Source).

Types of problems:

Supervised learning deals with two distinct kinds of problems:

  1. Classification problems
  2. Regression problems

 

Classification problem: In the case of classification problems, examples are classified into one or more classes/ categories.

For example, if we are trying to predict that a student will pass or fail based on their past profile, the prediction output will be “pass/fail.” Classification problems are often resolved using algorithms such as Naïve Bayes, Support Vector Machines, Logistic Regression, and many others.

Regression problem: A problem in which the output variable is either a real or continuous value, s is defined as a regression problem. Bringing back the student example, if we are trying to predict that a student will pass or fail based on their past profuse, the prediction output will be numeric, such as “68%” likely to score.

Predicting the prices of houses in an area is an example of a regression problem and can be solved using algorithms such as linear regression, non-linear regression, Bayesian linear regression, and many others.

Why Amazon, Netflix, and YouTube are great fans of supervised learning

Recommender systems are a notable example of supervised learning. E-commerce companies such as Amazon, streaming sites like Netflix, and social media platforms such as TikTok, Instagram, and even YouTube among many others make use of recommender systems to make appropriate recommendations to their target audience.

Unsupervised learning

Imagine receiving swathes of data with no obvious pattern in it. A dataset with no labels or target values cannot come up with an answer to what to predict. Does that mean the data is all waste? Nope! The dataset likely has many hidden patterns in it.

Unsupervised learning studies the underlying patterns and predicts the output. In simple terms, in unsupervised learning, the model is only provided with the data in which it looks for hidden or underlying patterns.

Unsupervised learning is most helpful for projects where individuals are unsure of what they are looking for in data. It is used to search for unknown similarities and differences in data to create corresponding groups.

An application of unsupervised learning is the categorization of users based on their social media activities.

Commonly used unsupervised machine learning algorithms include K-means clustering, neural networks, principal component analysis, hierarchical clustering, and many more.

Reinforcement learning

Another type of machine learning is reinforcement learning.

In reinforcement learning, algorithms learn in an environment on their own. The field has gained quite some popularity over the years and has produced a variety of learning algorithms.

Reinforcement learning is neither supervised nor unsupervised as it does not require labeled data or a training set. It relies on the ability to monitor the response to the actions of the learning agent.

Most used in gaming, robotics, and many other fields, reinforcement learning makes use of a learning agent. A start state and an end state are involved. For the learning agent to reach the final or end stage, different paths may be involved.

  • An agent may also try to manipulate its environment and may travel from one state to another
  • On success, the agent is rewarded but does not receive any reward or appreciation for failure
  • Amazon has robots picking and moving goods in warehouses because of reinforcement learning

Numerous IT companies including Google, IBM, Sony, Microsoft, and many others have established research centers focused on projects related to reinforcement learning.

Social media platforms like Facebook have also started implementing reinforcement learning models that can consider different inputs such as languages, integrate real-world variables such as fairness, privacy, and security, and more to mimic human behavior and interactions. (Source)

Amazon also employs reinforcement learning to teach robots in its warehouses and factories how to pick up and move goods.

Which is the better Machine Learning technique?

We learned about the three main members of the machine learning family essential for deep learning. Other kinds of learning are also available such as semi-supervised learning, or self-supervised learning.

Supervised, unsupervised, and reinforcement learning, are all used for different to complete diverse kinds of tasks. No single algorithm exists that can solve every problem, as problems of different natures require different approaches to resolve them.

Despite the many differences between the three types of learning, all of these can be used to build efficient and high-value machine learning and Artificial Intelligence applications. All techniques are used in different areas of research and development to help solve complex tasks and resolve challenges.
