NLP Tutorials — Part 9: Bi-LSTMs & GRUs

Hola! Welcome back to the follow-up article on LSTMs. In this article we shall discuss 2 more architectures which are very similar to LSTMs. They are Bi-LSTMs and GRUs (Gated Recurrent Units). As we saw in our previous article, the LSTM was able to solve most problems of vanilla RNNs and solve a few important NLP problems easily with good data. The Bi-LSTM and GRU can be treated as architectures which have evolved from LSTMs. The core idea will be the same with a few improvements here and there.
