OpenMatch/ance-tele_triviaqa_psg-encoder

This model is the passage encoder of ANCE-Tele trained on TriviaQA, described in the EMNLP 2022 paper "Reduce Catastrophic Forgetting of Dense Retrieval Training with Teleportation Negatives". The associated GitHub repository is available at https://github.com/OpenMatch/ANCE-Tele.

ANCE-Tele only trains with self-mined negatives (teleportation negatives) without using additional negatives (e.g., BM25, other DR systems) and eliminates the dependency on filtering strategies and distillation modules.

NQ (Test)	R@5	R@20	R@20
