Facets Overview

Facets Overview provides a wide range of statistics for each feature of a dataset. Facets Overview will help you detect missing data, zero values, non-uniformity in data distributions, and more, as we will see in this section.

We will begin by creating feature statistics for the training and testing datasets.

Creating feature statistics for the datasets

Without Facets Overview or a similar tool, the only way to obtain statistics would be to write our programs or use spreadsheets. Writing our own functions can be time-consuming and costly. This is where Facets provides statistics with a few lines of code that we will use now.

Implementing the feature statistics code

In this section, we will encode the data, stringify it, and build the statistics generator. When using JSON, we first stringify information to transfer data into strings before sending it to JavaScript functions.

First, we will import base64:

import base64
