17.09.2021 · BERT is a state-of-the-art model by Google that came in 2019. In this blog, I will go step by step to finetune the BERT model for movie reviews classification(i.e positive or negative ). Here, I will be using the Pytorch framework for the coding perspective. BERT is built on top of the transformer (explained in paper Attention is all you Need).
