Bidirectional LSTM

A Bidirectional LSTM (BiLSTM) is a sequence processing architecture that consists of two LSTMs: one taking the input in a forward direction, and the other taking it in a backward direction. This allows the network to capture both past and future context at any point in the sequence.

Frequently Asked Questions

What advantage does BiLSTM have over standard LSTM?

Standard LSTM only has access to past context. BiLSTM looks at both the words before and after a target word, resulting in a deeper contextual understanding.

Is BiLSTM used in generative models?

No, because generative models cannot look ahead into the future tokens they have not generated yet. They are primarily used for understanding and labeling tasks.
