看paper有点困惑，是先进行了RetroMAE的预训练，然后用无监督数据进行了dense retrieval的训练，然后又用self蒸馏进行了三种方式的训练吗？
Yes. RetroMAE->dense retrieval->unified fine-tuning
Yes. RetroMAE->dense retrieval->unified fine-tuning
Thanks for your reply! Do both bge and bge-m3 adopt a bi-encoder architecture? If so, is there actually a single roberta encoder or two seperate models?
bge and bge-m3 both are bi-encoder model, and query and passage share the same encoder.
