what are bidirectional recurrent layers in neural networks

Recipe Objective - What is Bidirectional Recurrent layers in neural network?

Bidirectional recurrent layers are defined as connecting two hidden layers of the opposite directions to same output. Because of this generative deep learning, output layer gets the information from past or backwards and the future or forward states simultaneously. Bidirectional recurrent layers or BRNNs do not require the input data to be fixed. Also, their future input information is reachable from current state. BRNN splits the neurons of a regular recurrent neural network into two directions where one for positive time direction or forward state and another for negative time direction or backward state. Those outputs of two states are not connected to inputs of the opposite direction states. BRNNs generative deep learning technique is more common in the supervised learning approaches, rather than the unsupervised or semi-supervised because It ,mentioned that how difficult it is to calculate a reliable probabilistic model.

This recipe explains what are bidirectional recurrent layers, how it is beneficial for neural network models and how it can be executed.

A Deep Dive into the Types of Neural Networks

Explanation of Bidirectional recurrent layers.

Stacking recurrent layers on the top of each other in Keras, all the intermediate layers should return their full sequence of the outputs that is a 3D tensor, rather than their output at last timestep. This is done by specifying return_sequences = TRUE command.

Stacking recurrent layers present the whole information which can be executed using Keras framework easily. It mitigating gorgetting issues at the deployment side and accuracy is increased using BRNN.
