Keras - Embedding Layer. It performs embedding operations in input layer. It is used to convert positive into dense vectors of fixed size. Its main application is in text analysis. The signature of the Embedding layer function and its arguments with default value is as follows, input_dim refers the input dimension.

Actually, setting mask_zero=True for the Embedding layer does not result in returning a zero vector. Rather, the behavior of the Embedding ...

03.10.2017 · Keras Embedding Layer. Keras offers an Embedding layer that can be used for neural networks on text data. It requires that the input data be integer encoded, so that each word is represented by a unique integer. This data preparation step can be performed using the Tokenizer API also provided with Keras.

If you're more interested in the "mechanics", the embedding layer is basically a matrix which can be considered a transformation from your discrete and sparse 1 ...
