Additionally, its being done to improve BERT performance regression when using Large Tensor Build 2) Leverages vectorization. Can't explain line by line as to how. Too much text to write. I can share a link about vectorization for reviewers to read. Let me know if you meant something else. I can write 1 line each for 3 cases which is necessary 3) I didn't understand this question. Could you clarify what meant by side-effect.
