Recurrent Neural Networks - Combination of RNN and CNN

Recurrent neural network (RNN) is a type of neural network where the output from previous step is fed as input to the current step. In traditional neural networks, all the inputs and outputs are independent of each other, but in some cases when it is required to predict the next word of a sentence, the previous words are necessary; hence, there is a need to recognize the previous words. Thus. Bidirectional Recurrent Neural Networks Mike Schuster and Kuldip K. Paliwal, Member, IEEE Abstract— In the first part of this paper, a regular recurrent neural network (RNN) is extended to a bidirectional recurrent neural network (BRNN).
