- A Bidirectional LSTM, or biLSTM, is a sequence processing model that consists of two LSTMs: one taking the input in a forward direction, and the other in a backwards direction. BiLSTMs effectively increase the amount of information available to the network, improving the context available to the algorithm (e.g. knowing what words immediately follow and precede a word in a sentence)

BiLSTM has become a popular architecture for many NLP tasks. An early application of BiLSTM was in the domain of speech recognition. Other applications include sentence classification, sentiment analysis, review generation, or even medical event detection in electronic health records. BiLSTM has been used for POS tagging and Word Sense Disambiguation (WSD) * 13*. RNN architectures like LSTM and BiLSTM are used in occasions where the learning problem is sequential, e.g. you have a video and you want to know what is that all about or you want an agent to read a line of document for you which is an image of text and is not in text format.
