What is recorded here?
Trained independent question and passage encoders from question-passage supervision and used dense similarity retrieval to supply evidence for an open-domain answer reader.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Dual encoders, dense similarity and BERT pretraining are inherited. Retrieval relevance is not answer truth, and dense retrieval does not universally dominate sparse BM25.
