MoR: Better Handling Diverse Queries with a Mixture of Sparse, Dense, and Human Retrievers

Jushaan Singh Kalra, Xinran Zhao, To Eun Kim +3

Retrieval-augmented Generation (RAG) is powerful, but its effectiveness hinges on which retrievers we use and how. Different retrievers offer distinct, often complementary signals:…
