Importing data

First, let's import the dataset. The IMDb movie reviews dataset is already provided in Keras, so we can import it directly:

from keras.datasets import imdb

The imdb class has a load_data main function, which takes in the following important argument:

• num_words: This is defined as the maximum number of unique words to be loaded. Only the n most common unique words (as they appear in the dataset) will be loaded. If n is small, the training time will be faster at the expense of accuracy. Let's set num_words = 10000.

The load_data function returns two tuples as the output. The first tuple holds the training set, while the second tuple holds the testing set. Note that the load_data function splits the data equally and randomly ...
