Towards Robust Tool Use in Agents via Experience-Driven Adaptive Guidance

Can Wang, Haoran Chen, Li Yu +4

The performance bottleneck of agents is increasingly shifting from model capability to the robustness of their execution processes. Tools play a central role as the primary interfa…

From Simple QA to Deep Research: A Verifiable Benchmark Constructed through Iterative Task Evolution

Can Wang, Haoran Chen, Haowen Gao +3

Deep research benchmarks require expert-level tasks and reliable evaluation grounded in task-specific knowledge. Existing benchmarks rely heavily on expert authoring or pre-existin…

A Gradient Perspective on RLVR Stability and Winner Advantage Policy Optimization

Prasanth YSS, Zhichen Ren, Rasa Hosseinzadeh +6

Reinforcement learning with verifiable rewards (RLVR) improves language-model reasoning, but GRPO-style optimization remains prone to collapse. We analyse this instability through…

SelfEvoSkill: Paired Execution Audits for Skill Revision without External Outcome Supervision

Haowen Gao, Haoran Chen, Can Wang +5

Agent skills provide LLM agents with reusable procedures, but a given skill may be incomplete, ineffective, or misleading for the current task. Existing methods for revising skills…

Remember Me, Refine Me: A Dynamic Procedural Memory Framework for Experience-Driven Agent Evolution

Zouying Cao, Jiaji Deng, Li Yu +4

Procedural memory enables large language model (LLM) agents to internalize "how-to" knowledge, theoretically reducing redundant trial-and-error. However, existing frameworks predom…

Auto-Rubric: Learning From Implicit Weights to Explicit Rubrics for Reward Modeling

Lipeng Xie, Sen Huang, Zhuo Zhang +9

Conventional reward modeling relies on gradient descent over neural weights, creating opaque, data-hungry "black boxes." We propose a paradigm shift from implicit to explicit rewar…

Voting with the Graph: Stable RLAIF via Topological Consistency Maximization

Boyin Liu, Zhuo Zhang, Sen Huang +8

Reinforcement Learning from AI Feedback (RLAIF) relies on LLM judges as preference measurement instruments, yet these instruments are fundamentally limited by random measurement er…
