At this point, let's take a quick look at the IMDb movie reviews dataset before we start building our model. It is always a good practice to understand our data before we build our model.
The IMDb movie reviews dataset is a corpus of movie reviews posted on the popular movie reviews website https://www.imdb.com/. Each movie review has a label indicating whether the review is positive (1) or negative (0).
The IMDb movie reviews dataset is provided in Keras, and we can import it by simply calling the following code:
from keras.datasets import imdb
training_set, testing_set = imdb.load_data(index_from = 3)
X_train, y_train = training_set
X_test, y_test = testing_set
We can print out the first movie review as follows:
print(X_train[0])
We'll see the following output:
[1, 14, 22, 16, 43, 530, 973, 1622, 1385, 65, 458, 4468, 66, 3941, 4, 173, 36...
