 We showcase several fine-tuning examples based on (and extended from) [the original implementation](https://github.com/google-research/bert/):
 
-- a sequence-level classifier on the MRPC classification corpus,
-- a token-level classifier on the question answering dataset SQuAD, and
-- a sequence-level multiple-choice classifier on the SWAG classification corpus.
