Bi-suffix in the component name stands for the bi-directional which means there exist two identical LSTM modules running on a given input on different directions. Concatenation of extracted features of LSTMs are the output of this component. Intuition behind this is to utilize the information exist in the rest of a given sequence since single LSTM extracts latent information using only elements in the sequence before that oneBack to article page
