MemChain: Learning Interpretable Memory Traces for Memory-Augmented LLM Agents

Yiwen Ma, Songjun Tu, Qichao Zhang +3

Memory-augmented LLM agents typically answer queries by retrieving relevant memories and feeding them directly to an answer model. This retrieval-as-evidence paradigm assumes retri…

UCOB: Learning to Utilize and Evolve Agentic Skills via Credit-Aware On-Policy Bidirectional Self-Distillation

Songjun Tu, Chengdong Xu, Qichao Zhang +6

Skill memories can improve agentic reinforcement learning by reusing past experience as textual guidance, but retrieved skills are not oracular: they may help in one state while mi…

Dynamic Dual-Granularity Skill Bank for Agentic RL

Songjun Tu, Chengdong Xu, Qichao Zhang +5

Agentic RL can benefit substantially from reusable experience, yet existing skill-based methods mainly extract trajectory-level guidance and often lack principled mechanisms for ma…

When to Vote, When to Rewrite: Disagreement-Guided Strategy Routing for Test-Time Scaling

Zhimin Lin, Yixin Ji, Jinpeng Li +5

Large Reasoning Models (LRMs) achieve strong performance on mathematical reasoning tasks but remain unreliable on challenging instances. Existing test-time scaling methods, such as…

: Unlocking LLM Reasoning via Reinforcement Learning with Re-solving

Pinzheng Wang, Shuli Xu, Juntao Li +4

Reinforcement learning with verifiable rewards (RLVR) has shown promise in enhancing the reasoning performance of large language models (LLMs) by increasing test-time compute. Howe…
