Keras

Keras is a widely popular high-level neural network API. It supports TensorFlow, CNTK, and Theano as the backend. Due to the user-friendly API of Keras, many people use it in lieu of the base libraries.

Embedding layer in Keras

The embedding layer will be the first hidden layer of the Keras network and you will need to specify three arguments: input dimension, output dimension, and input length. Since we will be using fastText to make our model better, we will also need to pass the weights parameter with the embedding matrix and make the trainable matrix to be false:

embedding_layer = Embedding(num_words,
                            EMBEDDING_DIM, 
                            weights=[embedding_matrix],
               ...
