Now, let's move on to the actual implementation where we need to load the data. Keras actually has a functionality that can be used to load this sentiment dataset from IMDb, but the problem is that it has already mapped all the words to integer tokens. This is such an essential part of working with natural human language insight neural networks that I really want to show you how to do it.
Also, if you want to use this code for sentiment analysis of whatever data you might have in some other language, you will need to do this yourself, so we have just quickly implemented some functions for downloading this dataset.
Let's start off by importing a bunch of required packages:
%matplotlib inlineimport matplotlib.pyplot ...
