Write, Execute, Refine: From Skill Followers to Skill Optimizers via Reinforcement Learning from Execution Feedback

Kang Peng, Zhiwei Zhang, Yichen Zhang +7

Expert-written natural language skills can improve tool-using agents, yet agent-authored skills perform 8-11 points worse than using no skill. This gap suggests that following proc…

EventWeave: A Dynamic Framework for Capturing Core and Supporting Events in Dialogue Systems

Zhengyi Zhao, Shubo Zhang, Yiming Du +5

Large language models have improved dialogue systems, but often process conversational turns in isolation, overlooking the event structures that guide natural interactions. Hence w…

ReSURE: Regularizing Supervision Unreliability for Multi-turn Dialogue Fine-tuning

Yiming Du, Yifan Xiang, Bin Liang +3

Fine-tuning multi-turn dialogue systems requires high-quality supervision but often suffers from degraded performance when exposed to low-quality data. Supervision errors in early…

WHERE and WHICH: Iterative Debate for Biomedical Synthetic Data Augmentation

Zhengyi Zhao, Shubo Zhang, Bin Liang +2

In Biomedical Natural Language Processing (BioNLP) tasks, such as Relation Extraction, Named Entity Recognition, and Text Classification, the scarcity of high-quality data remains…
