PreSO: Privileged Representation Isolation for On-Policy Self-Distillation

Yuhang Yang, Mingxuan Xia, Chao Ye +6

On-policy self-distillation (OPSD) uses a self-teacher conditioned on privileged information to turn the sparse outcome signal of reinforcement learning with verifiable rewards (RL…

DE-Venus: A Data-Efficient RLVR Framework for Large Language Models

Shenzhi Yang, Guangcheng Zhu, Kai Tang +11

Reinforcement learning with verifiable rewards (RLVR) improves large language model reasoning, but its practical scaling is constrained by expensive on-policy rollouts and the cost…

GeoMin: Data-Efficient Semi-Supervised RLVR via Geometric Distribution Modeling

Guangcheng Zhu, Shenzhi Yang, Haobo Wang +9

Reinforcement learning with verifiable rewards (RLVR) significantly advances LLM reasoning, yet it faces a dilemma: standard supervised scaling is throttled by high annotation cost…

A Syllogistic Probe: Tracing the Evolution of Logic Reasoning in Large Language Models

Zhengqing Zang, Yuqi Ding, Yanmei Gu +5

Human logic has gradually shifted from intuition-driven inference to rigorous formal systems. Motivated by recent advances in large language models (LLMs), we explore whether LLMs…

Parallelism and Generation Order in Masked Diffusion Language Models: Limits Today, Potential Tomorrow

Yangyang Zhong, Yanmei Gu, Zhengqing Zang +14

Masked Diffusion Language Models (MDLMs) promise parallel token generation and arbitrary-order decoding, yet it remains unclear to what extent current models truly realize these ca…
