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.
