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!

Evaluating the Robustness of Biomedical Concept Normalization

BERT is vulnerable to adversarial attacks and input transformations. This leads to the linkage of invalid inputs to concepts in an ontology. We study the robustness of different BERT-based Normalization models, including 13 different input transformations, and propose novel adversarial attacks. We found a significant drop in performance. Existing mitigation strategies are also explored.
