On-Policy Self-Distillation without Any Supervision

Yijiang Li, Bingyang Wang, Yijun Liang +3

On-policy (Self-)Distillation (OPD / OPSD) has shown strong potential for post-training large language models (LLMs). However, existing methods still rely heavily on external super…

Visual Contrastive Self-Distillation

Yijun Liang, Yunjie Tian, Yijiang Li +4

On-policy self-distillation (OPSD) is promising as it removes the external teacher required by on-policy distillation (OPD), yet it still needs asymmetric information between teach…

From RGB Generation to Dense Field Readout: Pixel-Space Dense Prediction with Text-to-Image Models

Zanyi Wang, Xin Lin, Haodong Li +2

Large-scale text-to-image models are attractive backbones for dense prediction because RGB generation pretraining learns rich semantic, structural, and geometric priors. Existing g…

RN-D: Discretized Categorical Actors for On-Policy Reinforcement Learning

Yuexin Bian, Jie Feng, Tao Wang +3

On-policy Reinforcement Learning (RL) remains a dominant paradigm for continuous control, yet standard implementations rely on Gaussian actors and relatively shallow MLP policies,…

SkillsBench: Benchmarking How Well Agent Skills Work Across Diverse Tasks

Xiangyi Li, Yimin Liu, Wenbo Chen +75

Agent Skills are structured packages of procedural knowledge that augment large language model (LLM) agents at inference time. Despite rapid adoption, there is no standard way to m…

Less is Enough: Synthesizing Diverse Data in LLM Feature Space with Sparse Autoencoders

Zhongzhi Li, Xuansheng Wu, Yijiang Li +2

The diversity of post-training data is critical for effective downstream performance in large language models (LLMs). Many existing approaches to constructing post-training data qu…
