Code Review Stack Exchange is a question and answer site for peer programmer code reviews. Bidirectional Recurrent Neural Networks (BRNN) connect two hidden layers of opposite directions to the same output.With this form of generative deep learning, the output layer can get information from past (backwards) and future (forward) states simultaneously.Invented in 1997 by Schuster and Paliwal, BRNNs were introduced to increase the amount of input information available to the network.
