The BERT framework uses a bidirectional transformer that allows it to learn the context of a word based on the left and right of the word. According to a paper by V. Sanh, et al., DistilBERT can \"reduce the size of a BERT model by 40%, while retaining 97% of its language understanding capabilities, and being 60% faster.\" This is why the DistilBERT model was used. For more information about the paper, please check out this [link](https://arxiv.org/abs/1910.01108).")
