Data preprocessing and data analysis

In this section, we will mainly cover data preprocessing and data analysis. As a part of data preprocessing, we are preparing our training dataset. You may be wondering what kind of data preparation I'm talking about, considering we already have the data. Allow me to tell you that we have two different datasets and both datasets are independent. So, we need to merge the DJIA dataset and NYTimes news article dataset in order to get meaningful insights from these datasets. Once we prepare our training dataset, we can train the data using different machine learning (ML) algorithms.

Now let's start the coding to prepare the training dataset. We will be using numpy, csv, JSON, and pandas as our dependency libraries. Here, our code is divided into two parts. First, we will prepare the dataset for the DJIA index dataset and then we will move to the next part, which is preparing the NYTimes news article dataset. During the preparation of the training dataset,...
