Column Type Annotation (CTA), which assigns a semantic type to a table column, underpins data integration, cleaning, and search over data lakes. State-of-the-art annotators are pre…
Optimizing Retrieval for RAG via Reinforcement Learning
Jiawei Zhou, Lei Chen
As retrieval-augmented generation (RAG) becomes more widespread, the role of retrieval is shifting from retrieving information for human browsing to retrieving context for AI reaso…
OpenRAG: Optimizing RAG End-to-End via In-Context Retrieval Learning
Jiawei Zhou, Lei Chen
In this paper, we analyze and empirically show that the learned relevance for conventional information retrieval (IR) scenarios may be inconsistent in retrieval-augmented generatio…
