New on-policy training method improves multi-hop retrieval for complex questions

Researchers have developed a new on-policy training method for embedding models used in multi-hop retrieval-augmented generation. This approach trains the model on its own potentially erroneous retrievals, aiming to improve its ability to find all necessary evidence for complex questions. The method showed improved performance on challenging variants of the HotpotQA and 2WikiMultiHopQA datasets, demonstrating a greater capacity to recover from its own mistakes. AI

IMPACT Enhances retrieval accuracy for complex, multi-document questions, potentially improving RAG system performance.

    Retrieving from Your Own Mistakes: On-Policy Training of Embedding Models for Multi-Hop Retrieval-Augmented Generation

    arXiv:2610.40409v1 Announce Type: new Abstract: Complex questions in retrieval-augmented generation require evidence spread over several documents, and an answer is reliable only when the retriever finds all of it. Chain embedding retrievers collect such evidence step by step, re…
