How does COCO-DR's zero-shot recall@5 on NQ and TriviaQA compare to supervised dense retrievers like DPR and C

Effective information retrieval (IR) from vast datasets relies on advanced techniques to extract relevant information in response to queries.Recent advancements in dense retrieval have showcased remarkable efficacy compared to traditional sparse retrieval methods.To further enhance retrieval performance, knowledge distillation techniques, often leveraging robust crossencoder rerankers, have been extensively explored.However, existing approaches primarily distill knowledge from pointwise rerankers, which assign absolute relevance scores to documents, thus facing challenges related to inconsiste

Research goal: How does COCO-DR's zero-shot recall@5 on NQ and TriviaQA compare to supervised dense retrievers like DPR and ColBERT-v2 when using a BEIR-style multi-dataset evaluation protocol?
