Don't Mix Rewards, Mix Policies: Policy Decomposition and Optimization for Multi-Reward RL

Ruiming Liang, Yi Zhong, Yizhen Yuan +6

Modern large language models (LLMs) are expected not just to answer correctly, but to adapt their behavior to different human values and use cases. As a result, multi-reward reinfo…

On-Policy Distillation with Curriculum Turn-level Guidance for Multi-turn Agents

Gengsheng Li, Mao Zheng, Mingyang Song +8

Multi-turn agents that plan, invoke tools, and interact with environments offer a promising paradigm for solving complex tasks, yet their capabilities typically rely on very large…

ResMerge: Residual-based Spectral Merging of Large Language Models

Yandu Sun, Zhiyan Hou, Haokai Ma +6

Model merging offers a training-free way to combine multiple post-trained expert models, but merging experts obtained through reinforcement learning (RL) remains challenging. Exist…

ST-Prune: Training-Free Spatio-Temporal Token Pruning for Vision-Language Models in Autonomous Driving

Lin Sha, Haiyun Guo, Tao Wang +4

Vision-Language Models (VLMs) have become central to autonomous driving systems, yet their deployment is severely bottlenecked by the massive computational overhead of multi-view c…
