Smaller Models, Better Rejects: Preference Distillation Scaling

Rui Cai, Wenhui Zhu, Xiwen Chen +15

Preference distillation typically treats a teacher response as preferred and the student's own response as rejected. This assumes that self-generated failures are the most informat…

Beyond Heuristic Tuning: Power-Calibrated LLM Watermarking

Xiaopu Wang, Zelin He, Chengyuan Liu +1

Logit-based watermarking is a widely used mechanism for identifying LLM generated content, yet its effectiveness is governed by a fundamental trade-off between detectability and se…

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…

AdaTrans: Feature-wise and Sample-wise Adaptive Transfer Learning for High-dimensional Regression

Zelin He, Ying Sun, Jingyuan Liu +1

We consider the transfer learning problem in the high dimensional linear regression setting, where the feature dimension is larger than the sample size. To learn transferable infor…
