DeBERTa

Another new approach to transformers can be found through disentanglement. Disentanglement in AI allows you to separate the representation features to make the training process more flexible. Pengcheng He, Xiaodong Liu, Jianfeng Gao, and Weizhu Chen designed DeBERTa, a disentangled version of a transformer, and described the model in an interesting article: DeBERTa: Decoding-enhanced BERT with Disentangled Attention: https://arxiv.org/abs/2006.03654

The two main ideas implemented in DeBERTa are:

Disentangle the content and position in the transformer model to train the two vectors separately
Use an absolute position in the decoder to predict masked tokens in the pretraining process

The authors provide the code on GitHub: https://github.com/microsoft/DeBERTa

DeBERTa exceeds the human baseline on the SuperGLUE leaderboard:
