• Decompose, Estimate, Select: Coverage-Aware Context Construction for Long-Form RAG — Retrieval-augmented generation (RAG) grounds a language model's output in retrieved evidence, but for complex questions spanning multiple aspects of an information need, relevance…
• xPRT: Cross-Passage Retrieval Pretraining — Dense retrievers are a foundational component underlying modern RAG and search systems. Training these models typically requires a curated collection of annotated query-document p…
• Beyond IPS: Reliable Counterfactual Evaluation in Multi-Stage Ad Systems without Logged Propensities — Offline evaluation of ad-ranking policies in multi-stage delivery systems is challenging because action propensities are often unavailable, limiting inverse propensity scoring (IP…
• R2QRec: Learning Recommendation Queries from Retrieval Feedback — Query-based recommendation separates expressing user needs from locating matching items. Its central learning problem is how to turn item interactions into effective retrieval req…
• Efficient LLM-based Subgraph Retrieval for Multi-Hop Knowledge Base Question Answering — Multi-hop Knowledge Base Question Answering (KBQA) aims to find answer entities in the knowledge base that are multiple hops away from the entities in the question. Information re…
