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…

Memory-T1: Reinforcement Learning for Temporal Reasoning in Multi-session Agents

Yiming Du, Baojun Wang, Yifan Xiang +11

Temporal reasoning over long, multi-session dialogues is a critical capability for conversational agents. However, existing works and our pilot study have shown that as dialogue hi…
