MLOps: A complete guide for building, deploying, and managing machine learning models
Saturn Cloud
| August 25, 2023

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.

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.

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.

MLOps out in industry

MLOps has been successfully implemented across various industries, driving significant improvements in efficiency, automation, and overall business performance. The following are real-world examples showcasing the potential and effectiveness of MLOps in different sectors:

Moody’s Analytics, a leader in financial modeling, encountered challenges such as limited access to tools and infrastructure, friction in model development and delivery, and knowledge silos across distributed teams. They developed and utilized ML models for various applications, including credit risk assessment and financial statement analysis. In response to these challenges, they implemented the Domino data science platform to streamline their end-to-end workflow and enable efficient collaboration among data scientists.

By leveraging Domino, Moody’s Analytics accelerated model development, reduced a nine-month project to four months, and significantly improved its model monitoring capabilities. This transformation allowed the company to efficiently develop and deliver customized, high-quality models for clients’ needs, like risk evaluation and financial analysis.

Entertainment with Netflix

Netflix utilized Metaflow to streamline the development, deployment, and management of ML workloads for various applications, such as personalized content recommendations, optimizing streaming experiences, content demand forecasting, and sentiment analysis for social media engagement. By fostering efficient MLOps practices and tailoring a human-centric framework for their internal workflows, Netflix empowered its data scientists to experiment and iterate rapidly, leading to a more nimble and effective data science practice.

According to Ville Tuulos, a former manager of machine learning infrastructure at Netflix, implementing Metaflow reduced the average time from project idea to deployment from four months to just one week.

This accelerated workflow highlights the transformative impact of MLOps and dedicated ML infrastructure, enabling ML teams to operate more quickly and efficiently. By integrating machine learning into various aspects of their business, Netflix showcases the value and potential of MLOps practices to revolutionize industries and improve overall business operations, providing a substantial advantage to fast-paced companies.

Mastering regularization in machine learning (2023 guide)
Muhammad Rizwan
| July 25, 2023

Regularization in machine learning is a technique that is used to prevent over fitting in ML models. In this article, we’ll explore what overfitting is and how regularization works to mitigate it, as well as the different types of regularization techniques used in machine learning.

Before we dive into the concept of regularization in machine learning, it’s important to first understand the related concepts of OVERFITTING and UNDERFITTING. These concepts are crucial for building accurate and reliable machine-learning models. If you want to know about machine learning in a layman manner please visit the below link as well. 

What is Overfitting? 

In machine learning, models are trained on a set of data called the training set. The goal is to create a model that can accurately predict outcomes on new data, called the test set. However, sometimes a model may become too complex and start fitting the training data too closely, essentially memorizing the data instead of learning from it. This is called overfitting, and it can lead to poor performance on new data.

What is Underfitting? 

On the other hand, Underfitting occurs when a machine learning model is too simple to capture the complexity of the data it is trying to model. This can happen when the model is not trained for long enough, or when the training data is not diverse enough to capture all the variations in the data. 

The ultimate goal of machine learning is to find the right balance between overfitting and underfitting, achieving a model that can generalize well to new data while still capturing the underlying patterns in the training data. This is known as achieving a “GENERALIZED” model. 

How does regularization in machine learning work?

Regularization works by adding a penalty term to the loss function during training. The penalty term discourages the model from creating complex relationships between the input features and the output variable. Essentially, it encourages the model to choose simpler solutions that generalize better to new data. By doing so, regularization can help prevent overfitting.

Types of regularization

There are several types of regularization techniques used in machine learning, including L1, L2, and dropout. 

Regularization Type Regularization Term Formula
L1 (Lasso)  

L1 Norm


(\text{L1 Regularization Term} = \alpha \sum_{i=1}^{n}

L2 (Ridge)


L2 Norm L2 Regularization Term=αi=1nwi21.

1. Lasso regularization (L1)

L1 regularization, commonly referred to as Lasso regularization, is a regularization technique extensively utilized in machine learning. It introduces a penalty term into the model’s cost function that is directly proportional to the absolute value of its weights. Consequently, larger weights incur a higher penalty. 

By promoting the reduction of non-zero weights, L1 regularization facilitates feature selection. This approach effectively simplifies the model by prioritizing significant features while eliminating irrelevant ones. Through penalizing large weights, the model is compelled to reduce their magnitudes, resulting in a less complex and more interpretable model. Ultimately, L1 regularization serves as a potent tool for enhancing the performance and interpretability of machine learning models. 

Code snippet for L1 regularization using Python and scikit-learn:

One noteworthy advantage of L1 regularization is its ability to streamline the model by reducing the number of utilized features. This can lead to faster training and improved generalization performance. However, it is essential to acknowledge that L1 regularization may not universally suit all data types and models, and alternative regularization techniques such as L2 regularization may be more suitable in certain scenarios. 

All in all, L1 regularization significantly contributes to improving model performance and interpretability, making it a valuable asset in the realm of data science. 

2. Ridge regularization (L2)

L2 regularization, commonly referred to as Ridge regularization, is a highly effective approach that enhances the performance of machine learning models. It achieves this by incorporating a penalty term that is directly proportional to the square of the model’s weights. This encourages the model to minimize the weight magnitudes, thereby preventing excessive complexity. As a result, L2 regularization effectively addresses the issue of overfitting and significantly improves the model’s ability to generalize to unseen data. 

Code snippet for L2 regularization using Python and scikit-learn: 

Compared to L1 regularization, L2 regularization does not perform feature selection by reducing the number of non-zero weights. Instead, it shrinks all the weights towards zero by a constant factor, thus making the model less sensitive to small fluctuations in the data. This technique is particularly useful when dealing with high-dimensional data, where the number of features is much larger than the number of observations, as it helps to avoid overfitting and improve the model’s generalization performance. 

Benefits of regularization

Regularization offers several advantages for machine learning models. Firstly, it effectively combats overfitting, allowing for better generalization on unseen data. This improves the model’s accuracy and enhances its practical applicability. 

Secondly, regularization aids in simplifying the model, making it more comprehensible and interpretable. This aspect is particularly valuable in domains like healthcare and finance, where model decisions have significant implications. 

Lastly, regularization mitigates the risk of biases in the model. By encouraging simpler solutions, it prevents the model from capturing spurious correlations in the data, which can lead to biased predictions. 


In a nutshell, regularization in machine learning plays a crucial role in machine learning as it helps address overfitting issues and enhances model accuracy, simplicity, and interpretability. It achieves this by introducing a penalty term to the loss function during training, promoting the selection of simpler solutions that can generalize well to unseen data.

Among the various regularization techniques, L2 regularization is widely employed in practice. In summary, regularization is an invaluable asset for machine learning practitioners and is expected to gain further prominence as the field advances. 

Machine learning model deployment 101: A comprehensive guide

| July 5, 2023

Machine Learning (ML) is a powerful tool that can be used to solve a wide variety of problems. However, building and deploying a machine-learning model is not a simple task. It requires a comprehensive understanding of the end-to-end machine learning lifecycle. 

The development of a Machine Learning Model can be divided into three main stages: 

  • Building your ML data pipeline: This stage involves gathering data, cleaning it, and preparing it for modeling. 
  • Getting your ML model ready for action: This stage involves building and training a machine learning model using efficient machine learning algorithms. 
  • Making sense of your ML model: This stage involves deploying the model into production and using it to make predictions. 
Machine Learning Model Deployment
Machine Learning Model Deployment

Building your ML data pipeline 

The first step of crafting a Machine Learning Model is to develop a pipeline for gathering, cleaning, and preparing data. This pipeline should be designed to ensure that the data is of high quality and that it is ready for modeling. 

The following steps are involved in pipeline development: 

  • Gathering data: The first step is to gather the data that will be used to train the model. For data scrapping a variety of sources, such as online databases, sensor data, or social media.
  • Cleaning data: Once the data has been gathered, it needs to be cleaned. This involves removing any errors or inconsistencies in the data. 

  • Exploratory data analysis (EDA): EDA is a process of exploring data to gain insights into its distribution, relationships, and patterns. This information can be used to inform the design of the model. 
  • Model design: Once the data has been cleaned and explored, it is time to design the model. This involves choosing the right machine-learning algorithm and tuning the model’s hyperparameters. 
  • Training and validation: The next step is to train the model on a subset of the data. Once the model has been trained, it can be evaluated on a holdout set of data to measure its performance. 

Getting your ML model ready for action  

Once the pipeline has been developed, the next step is to train the model. This involves using a machine learning algorithm to learn the relationship between the features and the target variable. 

The following steps are involved in training: 

  • Choosing a machine learning algorithm: There are many different machine learning algorithms available. The choice of algorithm will depend on the specific problem that is being solved. 
  • Tuning hyperparameters: Hyperparameters are parameters that control the behavior of the machine learning algorithm. These parameters need to be tuned to achieve the best performance. 
  • Training the model: Once the algorithm and hyperparameters have been chosen, the model can be trained on a dataset. 
  • Evaluating the model: Once the model has been trained, it can be evaluated on a holdout set of data to measure its performance. 

Making sense of ML model’s predictions 

Once the model has been trained, it can be deployed into production and used to make predictions. 

The following steps are involved in inference: 

  • Deploying the model: The model can be deployed in a variety of ways, such as a web service, a mobile app, or a desktop application. 
  • Making predictions: Once the model has been deployed, it can be used to make predictions on new data. 
  • Monitoring the model: It is important to monitor the model’s performance in production to ensure that it is still performing as expected. 


Developing a Machine Learning Model is a complex process, but it is essential for building and deploying successful machine-learning applications. By following the steps outlined in this blog, you can increase your chances of success. 

Here are some additional tips for building and deploying machine-learning models: 

  • Establish a strong baseline model. Before you deploy a machine learning model, it is important to have a baseline model that you can use to measure the performance of your deployed model. 
  • Use a production-ready machine learning framework. There are a number of machine learning frameworks available, but not all of them are suitable for production deployment. When choosing a machine learning framework for production deployment, it is important to consider factors such as scalability, performance, and ease of maintenance. 
  • Use a continuous integration and continuous delivery (CI/CD) pipeline. A CI/CD pipeline automates the process of building, testing, and deploying your machine-learning model. This can help to ensure that your model is always up-to-date and that it is deployed in a consistent and reliable manner. 
  • Monitor your deployed model. Once your model is deployed, it is important to monitor its performance. This will help you to identify any problems with your model and to make necessary adjustments 
  • Using visualizations to understand the insights better. With the help of the model many insights can be drawn, and they can be visualized using software like Power BI

Learn how the synergy of AI and Machine Learning algorithms in paraphrasing tools is redefining communication through intelligent algorithms that enhance language expression.

Artificial intelligence or AI as it is commonly called is a vast field of study that deals with empowering computers to be “Intelligent”.  This intelligence can manifest in different ways, but typically, it results in the automation of mundane tasks. However, the advancements in AI have led to automation in more sophisticated tasks as well. 

One of the most common applications of AI in a sophisticated task is text processing and manipulation. Which is also our topic today. Specifically, the paraphrasing of text with the help of AI. The most revolutionary technology that enables this is called machine learning. 

Machine learning algorithms
Machine learning algorithms

Machine learning is a subset of AI. So, when you say AI, it automatically includes machine learning as well. Now, we will take a look at how machine learning works in Paraphrasing tools. 

Role of machine learning in paraphrasing tools 

Machine learning by itself is also a vast field. There are a lot of ways in which a computer can process and manipulate text with machine learning algorithms.

You must have heard the name GPT if you are interested in text processing. GPT is one of the most popular machine-learning models used for text processing.  It belongs to a class of models called “Transformers” which are classified among deep learning models. 

And that was just one model. Transformers are the most popular when it comes to text processing and programmers have a lot of options to choose from. Many paraphrase generators nowadays utilize transformers in their back end for changing the given text. 

Most paraphrasing tools that are powered by AI are developed using Python because Python has a lot of prebuilt libraries for NLP (natural language processing).  

NLP is yet another application of machine learning algorithms. It allows computer systems to parse and understand text much in the same way a human would. So, let’s take a look at how a paraphrase generator works with these NLP libraries. We will check out a few different libraries and as such different transformers that are used nowadays for paraphrasing text.  

1. Pegasus Transformer

This is a part of the Transformers library available in Python 3. You can download Pegasus using pip with simple instructions. Machine learning algorithms will transform our lives, from autonomous vehicles to personalized medicine.

Pegasus was originally created for summarizing, however, the good thing about machine learning is that models can be tuned to do different things. So even though Pegasus is for summarizing, it can still be used for paraphrasing. 

Here’s how it works for paraphrasing. 

The transformer is trained on a large database of text, such a database is called a “corpus”. This corpus contains sentence pairs and each pair includes an original sentence and its paraphrased version. By training on such a corpus, the transformer learns how different sentences mean the same thing. Then it can create new paraphrases of any given sentence, even the ones it did not train on.  

2. T5 Transformer

T5 or text-to-text transfer transformer is a neural network architecture that can do a lot of things: 

  • Summarizing 
  • Translating 
  • Question and answering 
  • And of course, paraphrasing 

A paraphrasing tool that uses the T5 transformer can give a variety of different results because it is trained on a massive amount of data.  According to Google (the creators of T5), the T5 transformer was trained on Wikipedia, books, articles, and plenty of online web pages.  

T5 uses unsupervised learning which means it’s not told what is what, and it is allowed to draw its own conclusions. While that gives it extreme flexibility, it also gives more room for making errors. That’s why always proofread any text you get from a paraphrasing tool as it could have mistakes. 

3. Parrot Library

This particular library is not a transformer, but it uses similar techniques. It uses the same type of sequence-to-sequence architecture that is used in the T5 transformer.  

Another similarity between the two is that Parrot is also trained on a corpus of sentence pairs where one sentence is original and the other is paraphrased. This allows it to find patterns and realize that different syntax can still have the same meaning. 

Parrot uses a mix of supervised and unsupervised learning techniques. However, what sets Parrot apart from other models of paraphrasing is that it has two steps.  

Step one creates a bunch of paraphrases for the given text. However, it does not finalize them right away.  

Step 2 ranks the generated paraphrases and only selects the most highly ranked output. It uses a variety of factors to calculate rank and it is widely touted as one of the most accurate and fluent paraphrasing models available. 


So, now you know something about how machine learning algorithms work in paraphrasing tools. These models are running on the server side of these tools, so the end user cannot see what is happening. 

The tool forwards the input to the models, and they generate an output which is shown to the user. And that is the simplest description of paraphrasing with machine learning.

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.

Master hyperparameter tuning for machine learning models
Ayesha Saleem
| March 28, 2023

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.

Handling imbalanced data: 7 innovative techniques for successful analysis
Ayesha Saleem
| March 21, 2023

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.

Data science model deployment can sound intimidating if you have never had a chance to try it in a safe space. Do you want to make a rest API or a full frontend app? What does it take to do either of these? It’s not as hard as you might think. 

In this series, we’ll go through how you can take machine learning models and deploy them to a web app or a rest API (using saturn cloud) so that others can interact. In this app, we’ll let the user make some feature selections and then the model will predict an outcome for them. But using this same idea, you could easily do other things, such as letting the user retrain the model, upload things like images, or conduct other interactions with your model. 

Just to be interesting, we’re going to do this same project with two frameworks, voila and flask, so you can see how they both work and decide what’s right for your needs. In a flask, we’ll create a rest API and a web app version.

The project – Deploying machine learning models

The first steps of our process are exactly the same, whether we are going for voila or flask. We need to get some data and build a model! I will take the us department of education’s college scorecard data, and build a quick linear regression model that accepts a few inputs and predicts a student’s likely earnings 2 years after graduation. (you can get this data yourself at https://collegescorecard.ed.gov/data/) 

About measurements 

According to the data codebook: “the cohort of evaluated graduates for earnings metrics consists of those individuals who received federal financial aid, but excludes those who were subsequently enrolled in school during the measurement year, died before the end of the measurement year, received a higher-level credential than the credential level of the field of the study measured, or did not work during the measurement year.” 

Load data 

I already did some data cleaning and uploaded the features I wanted to a public bucket on s3, for easy access. This way, I can load it quickly when the app is run. 

Format for training 

Once we have the dataset, this is going to give us a handful of features and our outcome. We just need to split it between features and target with scikit-learn to be ready to model. (note that all of these functions will be run exactly as written in each of our apps.) 

 Our features are: 

  • Region: geographic location of college 
  • Locale: type of city or town the college is in 
  • Control: type of college (public/private/for-profit) 
  • Cipdesc_new: major field of study (cip code) 
  • Creddesc: credential (bachelor, master, etc) 
  • Adm_rate_all: admission rate 
  • Sat_avg_all: average sat score for admitted students (proxy for college prestige) 
  • Tuition: cost to attend the institution for one year 

Our target outcome is earn_mdn_hi_2yr: median earnings measured two years after completion of degree.

Train model 

We are going to use scikit-learn’s pipeline to make our feature engineering as easy and quick as possible. We’re going to return a trained model as well as the r-squared value for the test sample, so we have a quick and straightforward measure of the model’s performance on the test set that we can return along with the model object. 

Now we have a model, and we’re ready to put together the app! All these functions will be run when the app runs, because it’s so fast that it doesn’t make sense to save out a model object to be loaded. If your model doesn’t train this fast, save your model object and return it in your app when you need to predict. 

If you’re interested in learning some valuable tips for machine learning projects, read our blog on machine learning project tips.


In addition to building a model and creating predictions, we want our app to show a visual of the prediction against a relevant distribution. The same plot function can be used for both apps, because we are using plotly for the job. 

The function below accepts the type of degree and the major, to generate the distributions, as well as the prediction that the model has given. That way, the viewer can see how their prediction compares to others. Later, we’ll see how the different app frameworks use the plotly object. 


 This is the general visual we’ll be generating — but because it’s plotly, it’ll be interactive! 

Deploying machine learning models
Deploying machine learning models

You might be wondering whether your favorite visualization library could work here — the answer is, maybe! Every python viz library has idiosyncrasies and is not likely to be supported exactly the same for voila and flask. I chose plotly because it has interactivity and is fully functional in both frameworks, but you are welcome to try your own visualization tool and see how it goes.  

Wrapping up

In conclusion, deploying machine learning models to a web app or REST API can seem daunting, but it’s not as difficult as it may seem. By using frameworks like voila and Flask, along with libraries like scikit-learn, plotly, and pandas, you can easily create an app that allows users to interact with machine learning models. In this project, we used the US Department of Education’s college scorecard data to build a linear regression model that predicts a student’s likely earnings two years after graduation.

PolyBase is a feature that allows you to query and load data from different data sources, like Azure Blob Storage. This makes it optimal for handling large amounts of data or when speed is a priority.

Additionally, using a heap table for temporary data can improve loading speed. A heap table is a temporary table that only exists for a session and is useful when loading data to stage it before running more transformations. 


Clustered column store index

When loading data to a clustered column store table, creating a clustered column store index is essential for query performance. A clustered column store index is created on a table with a clustered column store architecture.  It is a highly compressed and in-memory storage format that stores each column of data separately, resulting in faster query processing and superior query performance. This helps to improve query performance by allowing the database engine to retrieve the required data pages more quickly. 


Managing compute costs

Managing computer costs is also important when working with dedicated SQL pools. One way to do this is by pausing and scaling the dedicated SQL pool. This allows you to only pay for the resources you need and can help you avoid unnecessary expenses. Additionally, using the appropriate resource class can improve query performance.

SQL pools use resource groups to allocate memory to queries. Initially, all users are assigned to the small resource class, which grants 100 MB of memory per distribution. However, more significant memory allocations will benefit certain queries, like large joins or loads to clustered column store tables. 


Maintaining statistics and performance tuning

To ensure optimal performance, it is essential to keep statistics updated when using dedicated SQL pools. The quality of the query plans generated by the optimizer depends on the accuracy of the statistics, so it is necessary to make sure statistics on columns used in queries are current. Performance tuning is another crucial aspect of working with dedicated SQL pools.

One way to improve query performance is using materialized views, ordered clustered column store index, and result set caching. Additionally, it is a good practice to group INSERT statements into batches to optimize large amounts of data loading. 


Hash distributes large tables and partitioning data

When using dedicated SQL pools, it is recommended to hash-distribute large tables instead of relying on the default Round Robin distribution. It is also important to be mindful when partitioning data, as too many partitions can impact performance negatively. Partitioning can be beneficial for managing data through partition switching or optimizing scans, but it should be done carefully. 



In conclusion, working with dedicated SQL pools in Azure Synapse Analytics requires a comprehensive understanding of best practices for loading data, managing compute costs, utilizing PolyBase, maintaining statistics, performance tuning, hash distributing large tables, and partitioning data.

By following these best practices, you can achieve optimal performance and reduce costs with your dedicated SQL pools in Azure Synapse Analytics. It is important to remember that Azure Synapse Analytics is a complex platform. These best practices will help you in your data processing and analytics journey.

Social media recommendation systems: The key to unlocking user engagement
Ahsan Manzoor
| January 2, 2023

Billions of users use various social media daily and see a lot of new suggestions there. The content includes text, images, videos, and so on depending on the social platform. Do you know how that content is suggested? 

We will learn about it in this blog.

Recommendation system: 

It is an algorithm that suggests relevant products to users based on a variety of factors. Sometimes, when you search for a certain product on a website you notice that you start receiving several suggestions of similar products, there is a system behind this. It is generally used to target potential users more efficiently and improve the user experience by suggesting new items, saving users’ time, and narrowing down the set of choices.

Watch the video to see what a recommendation system is and how it is used in various real-world applications. 


Introduction to Recommender Systems 



Now that we know the concept, let’s dive deeper into a real-world application to better comprehend it. 


YouTube’s recommendation system journey

YouTube has over 800 million videos, which is about 17,810 years of continuous video watching. It is hard for a user to repeatedly search for certain sorts of videos from millions of videos. This problem is solved by recommendation systems, which provide relevant videos based on what you are currently watching.

The system also works when you open YouTube’s home page and do not watch any videos. In this case, it shows the mixture of the subscribed, most up-to-date, promoted, and most recently watched videos.  

Let’s discuss the journey of the recommendation system on YouTube. 

In 2008, YouTube’s recommendation system ranked videos based on popularity. The issue with this approach was sometimes violent or racy videos get popular. To avoid this, YouTube built classifiers to identify this type of content and avoid recommending them. After a couple of years, YouTube started to incorporate video watch time in its recommendation system.

The reason for this was that users often watched different types of videos and there were different recommendations for them. Later, YouTube took surveys where users rated the watched videos and answered the questions upon giving low or high stars.  

Soon, YouTube’s management realized that everyone did not fill out the survey. So, YouTube trained a machine learning model on completed surveys and predicted the survey responses. YouTube did not stop there; they started to consider the likes/dislikes and share information to make the recommender system better.  

Nowadays, they are also using classifiers to identify authoritative and borderline (doesn’t quite violate community) content to make a better recommender system.

Before diving deep into the technical detail, let’s first discuss common types of recommendation systems. 

Classification of recommendation system:  

Recommendation system
Recommendation system


These types of recommendation systems are widely used in industry to solve different problems. We will go through these briefly. 


1. Content-based recommendation system

 According to the user’s past behavior or explicit feedback, content-based filtering uses item features (such as keywords, categories, etc.) to suggest additional items that are similar to what they already enjoy. 

Content based recommendation system

2. Collaborative recommendation system 

Collaborative filtering gives information based on interactions and data acquired by the system from other users. It is divided into two types: memory-based, and model-based systems. 


a) Memory-based system 

This mechanism is further classified as user-based and item-based filtering. In the user-based approach, recommendations are made based on the user’s preferences that are similar to the preferences of other users. In the item-based approach, recommendations are made based on items similar to other items the active user likes. 


Let’s see the below illustration to understand the difference:  

User-based recommendation system
User-based and item-based recommendation system


b) Model-based system 

This mechanism provides recommendations by developing machine learning models from users’ ratings. A few commonly used machine learning models are clustering-based, matrix factorization-based, and deep learning models.  

Model-based system
Model-based system

2. Demographic-based recommendation system 

This system provides recommendations based on user demographic attributes, such as age, sex, and location. This system uses demographic information, such as a user’s age, gender, and location, to provide personalized recommendations. This type of system uses data about a user’s characteristics to suggest items that may be of particular interest to them.

For example, a recommendation system might use a user’s age and location to suggest events or activities in the user’s area that might be of interest to someone in their age group.



3. Knowledge-based recommendation system 

This system offers recommendations based on queries made by the user rather than a user’s rating history. Shortly, it is based on explicit knowledge of the item variety, user preference and suggestion criteria. This strategy is suited for complex domains where products are not acquired frequently, such as houses and automobiles. 


4. Community-based recommendation system 

This system provides recommendations based on user-interacted items within a community that shares a common interest. A community-based recommendation system is a tool that uses the interactions and preferences of a group of people with a shared interest to provide personalized recommendations to individual users.

This type of system takes into account the collective experiences and opinions of the community in order to provide personalized recommendations.


5. Hybrid recommendation system 

This system is a combination of two or more discussed recommendation systems such as content-based, collaborative-based, and so on. Sometimes a single recommendation system cannot solve an issue, thus we must combine two or more recommendation systems. 

We now have a high-level understanding of the various recommendation systems. Recall the YouTube discussion, what do you think, which recommendation method suits YouTube the most. 


It is a memory-based collaborative recommendation system. YouTube can use an item-based approach to suggest videos based on other similar videos using users’ ratings (clicked on and watched videos). To determine the most similar match, we can use matrix factorization. This is a class of collaborative recommendation systems to find the relationship between items’ and users’ entities. However, this approach has numerous limitations, such as  

  • Not being suitable for complex relations in the users and items 
  • Always recommend popular items 
  • Cold start problem (cannot anticipate items and users that we have never encountered in training data) 
  • Can only use limited information (only user IDs and item IDs)  

To address the shortcomings of the matrix factorization method, deep neural networks are designed and used by YouTube. Deep learning is based on artificial neural networks, which enable computers to comprehend and make decisions in the same way that the human brain does.

Let’s watch the video below to gain a better understanding of deep learning.



YouTube uses the deep learning model for its video recommendation system. They provide users’ watch history and context to the deep neural network. The network then learns from the provided data and uses the softmax classifier (used for multiclass classification) to differentiate among the videos. This model provides hundreds of videos from a pool of over 800 million videos. This procedure was named “candidate generation” by YouTube.  

But we just need to reveal a few of them to a certain user. So, YouTube created a ranking system in which they provide a rank (score) to each of a few hundred videos. They used the same deep learning model that assigns a score to each video for this. The score may be based on the video that the user watched from any channel and/or the most recently watched video topic.

We studied different recommendation systems that can be used to address various real-world challenges. These systems help to connect people with resources and information that may not have been easily discoverable otherwise, making them a useful tool for solving these challenges.

We discussed the journey of YouTube’s recommendation system, a collaborative system used by YouTube, and examined how YouTube performed well using deep learning in their systems.

Key statistical distributions with real-life scenarios
Ayesha Saleem
| December 8, 2022

Statistical distributions help us understand a problem better by assigning a range of possible values to the variables, making them very useful in data science and machine learning. Here are 6 types of distributions with intuitive examples that often occur in real-life data. 

In statistics, a distribution is simply a way to understand how a set of data points are spread over some given range of values.  

For example, distribution takes place when the merchant and the producer agree to sell the product during a specific time frame. This form of distribution is exhibited by the agreement reached between Apple and AT&T to distribute their products in the United States.

Types of statistical distributions 

There are several statistical distributions, each representing different types of data and serving different purposes. Here we will cover several commonly used distributions. 

  1. Normal Distribution 
  2. t-Distribution 
  3. Binomial Distribution 
  4. Poisson Distribution 
  5. Uniform Distribution 


Pro-tip: Enroll in the data science bootcamp today and advance your learning 


1. Normal Distribution 

A normal distribution also known as “Gaussian Distribution” shows the probability density for a population of continuous data (for example height in cm for all NBA players). Also, it indicates the likelihood that any NBA player will have a particular height. Let’s say fewer players are much taller or shorter than usual; most are close to average height.  

The spread of the values in our population is measured using a metric called standard deviation. The Empirical Rule tells us that: 

  • 68.3% of the values will fall between1 standard deviation above and below the mean 
  • 95.5% of the values will fall between2 standard deviations above and below the mean 
  • 99.7% of the values will fall between3 standard deviations above and below the mean 


Let’s assume that we know that the mean height of all players in the NBA is 200cm and the standard deviation is 7cm. If Le Bron James is 206 cm tall, what proportion of NBA players is he taller than? We can figure this out! LeBron is 6cm taller than the mean (206cm – 200cm). Since the standard deviation is 7cm, he is 0.86 standard deviations (6cm / 7cm) above the mean. 

Our value of 0.86 standard deviations is called the z-score. This shows that James is taller than 80.5% of players in the NBA!  

This can be converted to a percentile using the probability density function (or a look-up table) giving us our answer. A probability density function (PDF) defines the random variable’s probability of coming within a distinct range of values. 


2. t-distribution 

A t-distribution is symmetrical around the mean, like a normal distribution, and its breadth is determined by the variance of the data. A t-distribution is made for circumstances where the sample size is limited, but a normal distribution works with a population. With a smaller sample size, the t-distribution takes on a broader range to account for the increased level of uncertainty. 

The number of degrees of freedom, which is determined by dividing the sample size by one, determines the curve of a t-distribution. The t-distribution tends to resemble a normal distribution as sample size and degrees of freedom increase because a bigger sample size increases our confidence in estimating the underlying population statistics. 

For example, suppose we deal with the total number of apples sold by a shopkeeper in a month. In that case, we will use the normal distribution. Whereas, if we are dealing with the total amount of apples sold in a day, i.e., a smaller sample, we can use the t distribution. 


3. Binomial distribution 

A Binomial Distribution can look a lot like a normal distribution’s shape. The main difference is that instead of plotting continuous data, it plots a distribution of two possible discrete outcomes, for example, the results from flipping a coin. Imagine flipping a coin 10 times, and from those 10 flips, noting down how many were “Heads”. It could be any number between 1 and 10. Now imagine repeating that task 1,000 times. 

If the coin, we are using is indeed fair (not biased to heads or tails) then the distribution of outcomes should start to look at the plot above. In the vast majority of cases, we get 4, 5, or 6 “heads” from each set of 10 flips, and the likelihood of getting more extreme results is much rarer! 


4. Bernoulli distribution 

The Bernoulli Distribution is a special case of Binomial Distribution. It considers only two possible outcomes, success, and failure, true or false. It’s a really simple distribution, but worth knowing! In the example below we’re looking at the probability of rolling a 6 with a standard die.

If we roll a die many, many times, we should end up with a probability of rolling a 6, 1 out of every 6 times (or 16.7%) and thus a probability of not rolling a 6, in other words rolling a 1,2,3,4 or 5, 5 times out of 6 (or 83.3%) of the time! 


5. Discrete uniform distribution: All outcomes are equally likely 

Uniform distribution is represented by the function U(a, b), where a and b represent the starting and ending values, respectively. Like a discrete uniform distribution, there is a continuous uniform distribution for continuous variables.  

In statistics, uniform distribution refers to a statistical distribution in which all outcomes are equally likely. Consider rolling a six-sided die. You have an equal probability of obtaining all six numbers on your next roll, i.e., obtaining precisely one of 1, 2, 3, 4, 5, or 6, equaling a probability of 1/6, hence an example of a discrete uniform distribution. 

As a result, the uniform distribution graph contains bars of equal height representing each outcome. In our example, the height is a probability of 1/6 (0.166667). 

The drawbacks of this distribution are that it often provides us with no relevant information. Using our example of a rolling die, we get the expected value of 3.5, which gives us no accurate intuition since there is no such thing as half a number on a dice. Since all values are equally likely, it gives us no real predictive power. 

It is a distribution in which all events are equally likely to occur. Below, we’re looking at the results from rolling a die many, many times. We’re looking at which number we got on each roll and tallying these up. If we roll the die enough times (and the die is fair) we should end up with a completely uniform probability where the chance of getting any outcome is exactly the same 


6. Poisson distribution 

A Poisson Distribution is a discrete distribution similar to the Binomial Distribution (in that we’re plotting the probability of whole numbered outcomes) Unlike the other distributions we have seen however, this one is not symmetrical – it is instead bounded between 0 and infinity.  

For example, a cricket chirps two times in 7 seconds on average. We can use the Poisson distribution to determine the likelihood of it chirping five times in 15 seconds. A Poisson process is represented with the notation Po(λ), where λ represents the expected number of events that can take place in a period.

The expected value and variance of a Poisson process is λ. X represents the discrete random variable. A Poisson Distribution can be modeled using the following formula. 

The Poisson distribution describes the number of events or outcomes that occur during some fixed interval. Most commonly this is a time interval like in our example below where we are plotting the distribution of sales per hour in a shop. 



Data is an essential component of the data exploration and model development process. We can adjust our Machine Learning models to best match the problem if we can identify the pattern in the data distribution, which reduces the time to get to an accurate outcome.  

Indeed, specific Machine Learning models are built to perform best when certain distribution assumptions are met. Knowing which distributions, we’re dealing with may thus assist us in determining which models to apply. 

Load testing with Locust – A modern tool for quality assurance 
Saad Shaikh
| November 26, 2022

 Data Science Dojo is offering Locust for FREE on Azure Marketplace packaged with pre-configured Python interpreter and Locust web server for load testing. 


Why and when do we perform testing? 

Testing is an evaluation and confirmation that a software application or product performs as intended. The purpose of testing is to determine whether the application satisfies business requirements and whether the product is market ready. Applications can be subjected to automated testing to see if they meet the demands. Scripted sequences are used in this method of software testing, and testing tools carry them out. 

The merits of automated testing are: 

  • Bugs can be avoided 
  • Development costs can be reduced 
  • Performance can be improved till requirement 
  • Application quality can be enhanced 
  • Development time can be saved 

Testing is usually the last phase of the SDLC (Software Development Life Cycle)  

What is load testing and why choose Locust?  

Performance testing is one of several types of software testing. Load testing is an example of performance testing to evaluate performance under real-life load conditions. It involves the following stages: 

  • Define crucial metrics and scenarios 
  • Plan the test load model 
  • Write test scenarios 
  • Execute test by swarming load 
  • Analyze the test results 

It is a modern load testing framework. The major reason senior testers prefer it over other tools like JMeter is because it uses an event-based approach for testing rather than thread based. This results in less consumption of resources and thus saves costs.

Challenges faced by QA teams  

Before such feasible testing tools, the job of testing teams was not much easier as it is now. Swarming a large number of users to direct as a load on a website was expensive and time-consuming.  

Apart from this, monitoring the testing process in real time was not prevalent either. Complete analytics were usually drawn after the whole testing process concludes, which again required patience. 

The testers needed a platform through which they can evaluate quality of product and its compliance with the specified requirements under different loads without the prolonged wait and high expense. 

Working of Locust 

Locust is an open-source web-based load testing tool. It is based on python and is used to evaluate the functionality and behavior of the web application. For the quality assurance process in any business, load testing is an extremely critical element to assure that the website remains up during traffic influx as it will eventually contribute to the success of the company. Through Locust, web testers can determine the potential of the website to withstand the number of concurrent users. With the power of python, you can develop a set of test scenarios and functions that imitate many users and can observe performance charts on web UI.

With the surge in demand and interest in AI and machine learning, many contemporary trends are emerging in this space. As a tech professional, this blog will excite you to see what’s next in the realm of Artificial Intelligence and Machine Learning trends.


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   


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


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.

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.

Mathematics for machine learning

Mathematics for Machine Learning is a tool that helps you understand the mathematical foundations of machine learning, so that you
can build better models and algorithms. It covers topics such as linear algebra, probability, optimization, and statistics. With this book, you
will be able to learn the mathematics needed to develop machine learning models and algorithms. Daniel – Founder, Gadget FAQs

This book is excellent for brushing up your mathematics knowledge required for ML. It is very concise while still providing enough details to help readers determine important parts. This is the go-to if you need to review some concepts or brush up on my knowledge in general.

This book is not recommended if you have absolutely no prior math experience though as it can be hard to digest and sometimes, they would skip parts here and there in proofs and examples. Especially for the probability section, the concepts will be very hard to grasp without prior knowledge

3. Linear Algebra and Optimization for Machine Learning

This textbook provides a comprehensive introduction to linear algebra and optimization, two fundamental topics in machine learning. It
covers both theory and applications and is suitable for students with little or no background in mathematics. Allan McNabb, VP – Image Building Media

The book begins with a review of basic linear algebra, before moving on to more advanced topics such as matrix decompositions, eigenvalues and eigenvectors, singular value decomposition, and least squares methods. Optimization techniques are then introduced, including gradient descent, Newton’s Method, conjugate gradient methods, and interior point methods.

4. The Hundred-Page Machine Learning Book

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

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 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 with 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

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

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.
