Wrapping up

In this blog post, we have reviewed the top 6 AI tools for data analysis. These tools offer a variety of features and capabilities, so the best tool for a particular project will depend on the specific requirements of the project.

However, all of these AI tools can be used to help businesses make better decisions by providing insights into their data. As AI continues to evolve, we can expect to see even more powerful and sophisticated tools that can help us analyze data more efficiently and effectively. When selecting the right AI tool for data analysis, it is important to consider the following factors:

• The level of expertise of your team
• Your budget

Machine learning is a powerful tool that helps organizations make informed decisions based on data. However, building and deploying machine learning models can be a complex and time-consuming process. This is where drag-and-drop tools come in. These tools provide a visual interface for building machine learning pipelines, making the process easier and more efficient for data scientists. 

Below, we will cover the different components of a machine learning pipeline, including data inputs, preprocessing steps, and models, and how they can be easily connected using drag-and-drop tools. We will also examine the benefits of using these tools, including ease of use, improved accuracy, and faster deployment. 

 

What are drag and drop tools?

Drag and drop tools are user-friendly software that allows users to build machine learning pipelines by simply dragging and dropping components onto a canvas. These tools let users visualize the workflow and track the pipeline’s progress. The benefits of using drag-and-drop tools in machine learning pipelines include quick model development, improved accuracy, and improved productivity. 

How do drag and drop tools work? 

Drag and drop tools for machine learning pipelines work by providing a visual interface for building and managing the pipeline. The interface typically consists of a canvas on which components, such as data inputs, preprocessing steps, and models, are represented as blocks that can be dragged and dropped into place. The user can then easily connect these blocks to define the flow of the pipeline. 

The process of building a machine learning pipeline with a drag-and-drop tool usually starts with selecting the data source. Once the data source is selected, the user can then add preprocessing steps to clean and prepare the data. The next step is to select the machine learning algorithm to be used for the model. Finally, the user can deploy the model and monitor its performance. 

One of the main benefits of using drag-and-drop tools in machine learning pipelines is the ease of use. These tools are designed to be user-friendly and do not require any coding skills, making it easier for data scientists to build models quickly and efficiently.

Additionally, the visual representation of the pipeline provided by these tools makes it easier to identify potential errors and improve the accuracy of the models. In summary, drag-and-drop tools provide a visual and intuitive way to build and manage machine learning pipelines, making the process easier and more efficient for data scientists.

This tutorial will walk you through building a classification model in Azure ML Studio by using the same process as a traditional data mining framework.

Using Azure ML studio (Overview)

We will use the public Titanic dataset for this tutorial. From the dataset, we can build a predictive model that will correctly classify whether you will live or die based upon a passenger’s demographic features and circumstances.

Would you survive the Titanic disaster?

About the data

We use the Titanic dataset in our data science bootcamp, and have found it is one of the few datasets that is good for both beginners and experts because its complexity scales up with feature engineering. There are numerous public resources to obtain the Titanic dataset, however, the most complete (and clean) version of the data can be obtained from Kaggle, specifically their “train” data.

The train Titanic data has 891 rows, each one pertaining to a passenger on the RMS Titanic on the night of its disaster. The dataset also has 12 columns that each record an attribute about each occupant’s circumstances and demographics: user ID, passenger class, age, gender, name, number of siblings and spouses aboard, number of parents and children aboard, fare price, ticket number, cabin number, their port of embarkation, and whether they survived the ordeal or not.

For additional reading, a repository of biographies pertaining to everyone aboard the RMS Titanic can be found here (complete with pictures).

Preprocessing & data exploration

Drop low-value columns

Begin by identifying columns that add little-to-no value for predictive modeling. These columns will be dropped.

The first, most obvious candidate to be dropped is PassengerID. No information was provided to us as to how these keys were derived. Therefore, the keys could have been completely random and may add false correlations or noise to our model.

The second candidate for removal is the passenger Name column. Normally, names can be used to derive missing values of gender, but the gender column holds no empty values. Thus, this column is of no use to us, unless we use it to engineer another name column.

The third candidate for removal will be the Ticket column, which represents the ticket serial ID. Much like PassengerID, information is not readily available as to how these ticket strings were derived. Advanced users may dig into historical documents to investigate how the travel agencies set up their ticket names, perform a clustering analysis, or bin the ticket values. Those techniques are out of the scope of this experiment.

The last candidate to be dropped will be Cabin, which is the cabin number where the passenger stayed. Although this column may hold value when binned, there are 147 missing values in this column (~21% of the data). Advanced users may cluster the cabins by letters, or can dig down into the grit of the actual RMS Titanic ship schematics to derive useful features such as cabin distance from hull breach or average elevation from sea level.

Define categorical variables

We must now define which values are non-continuous by casting them as categorical. Mathematical approaches for continuous and non-continuous values differ greatly. For example, if we graph the “Survived” column now, it will look funny because it would try to account for the range between “0” and “1”. However, being partially alive in this case would be absurd. Categorical values are looked at independently of one another as “choices” or “options” rather than as a numeric range.

For a quick (but not exhaustive) exercise to see if something should be categorical, simply ask, “Would a decimal interval for this value make sense?”

From this exercise, the columns that should be cast as categorical are: Survived, Pclass, Sex, and Embarked. The trickiest of these to determine might have been Pclass because it’s a numerical value that goes from 1 to 3. However, it does not really make sense to have a 2.5 Class between the second class and third class. Also, the relationship or “distance” between each interval of PClass is not explicit.

To cast these columns, drag in the “Edit Metadata” module. Specify the columns to be cast, then change the “Categorical” parameter to “Make categorical”.

Clean missing data in Azure ML

Most algorithms are unable to account for missing values and some treat it inconsistently from others. To address this, we must make sure our dataset contains no missing, “null,” or “NA” values. There are many ways to address missing values. We will cover three: replacement, exclusion, and deletion.

We used exclusion already when we made a conscious decision not to use “Cabin” attributes by dropping the column entirely.

Replacement is the most versatile and preferred method because it allows us to keep our data. It also minimizes collateral damage to other columns as a result of one cell’s bad behavior. In replacement, numerical values can easily be replaced with statistical values such as mean, median, or mode. The median is usually preferred for machine learning because it preserves the distribution of the data and is less affected by outliers. However, the median will skew and overload your frequencies, meaning it’ll mess with your bar graph but not your box plot.

We will cover deletion later in this section.

Now we can hunt for missing values. Drag in a “Summarize Data” module and connect it to your “Edit Metadata” module. Run the experiment and visualize the summary output. You will get a column summarizing the “missing value count” for each attribute. At this point, there are 177 missing values for “Age” and 2 missing values for “Embarked.”
