When LLMs Read Tables Carelessly: Measuring and Reducing Data Referencing Errors

Yuqing Yang, Qi Zhu, Zhen Han +5

While large language models (LLMs) perform well on table tasks, they still make data referencing errors (DREs), i.e., incorrectly citing or omitting table values, despite understan…

LLMZero: Discovering Adaptive Training Strategies for RL Post-Training via LLM Agents

Haoyang Fang, Wei Zhu, Boran Han +11

RL post-training strategies are dataset-dependent and reveal a recurring empirical pattern: capacity parameters accumulate monotonically across stages, while regularization paramet…

ReSkill: Reconciling Skill Creation with Policy Optimization in Agentic RL

Zelin He, Haotian Lin, Boran Han +6

Agentic reinforcement learning (RL) enables LLM agents to improve continuously from environment rewards, yet the resulting policies do not systematically accumulate reusable strate…

CrEst: Credibility Estimation for Contexts in LLMs via Weak Supervision

Dyah Adila, Shuai Zhang, Boran Han +2

The integration of contextual information has significantly enhanced the performance of large language models (LLMs) on knowledge-intensive tasks. However, existing methods often o…
