Structure of the model

The author improve thefine-tuning of BERT with two effective mechanisms:self-ensembleandself-distillation. The experimentson text classification and natural language inferencetasks show our proposed methods can significantlyimprove the adaption of BERT without any externaldata or knowledge.
