Why bidirectional RNN is better than unidirectional RNN: A theoretical proof

Ever wondered how Machine Learning research papers come up with their own mathematical proofs? In this article, we will provide you with a step-by-step, theoretical proof of why a bidirectional Recurrent Neural Network (RNN) performs empirically better than a unidirectional RNN. Our proof is novel and does not exist in Deep Learning literature. By going through this article, you will learn how to write your own proofs!
