1. Mitigating Lost-in-Retrieval Problems in Retrieval Augmented Multi-Hop Question Answering (2025 · 16 citations)
   In retrieval-augmented multi-hop QA, LLMs often split a complex question into sub-questions. Later sub-questions then refer to an earlier result through a pronoun such as "this author" instead of naming the entity. The authors call this failure "lost-in-retrieval." Without the key entity, retrieval for these…
2. Asymmetric On-Policy Distillation: Bridging Exploitation and Imitation at the Token Level (2026 · 6 citations)
   On-policy distillation (OPD) lets a small student learn from its own sampled outputs, with a teacher scoring each token by the gap between their log-probabilities.
