Advanced Recurrent Neural Networks: Bidirectional RNNs

Editors note: This article was originally written in 2021, and some of its conjectures may be outdated. The core theory and code remain relevant and executable, respectively.

In this tutorial we’ll cover bidirectional RNNs: how they work, the network architecture, their applications, and how to implement bidirectional RNNs using Keras.

Specifically, we’ll cover:

• An overview of RNNs
• LSTM and GRU Blocks
• The need for bidirectional traversal
• Bidirectional RNNs
• Sentiment analysis using a bidirectional RNN
• Conclusion

Let’s get started!
