GD2PO: Mitigating Multi-Reward Conflicts via Group-Dynamic reward-Decoupled Policy Optimization

Haotian Liu, Yihao Liu, Jingwei Ni +11

As LLMs advance, post-training reinforcement learning (RL) increasingly relies on multi-dimensional rewards to cultivate comprehensive capabilities. This shift demands new algorith…

Eliminating Inductive Bias in Reward Models with Information-Theoretic Guidance

Zhuo Li, Pengyu Cheng, Zhechao Yu +7

Reward models (RMs) are essential in reinforcement learning from human feedback (RLHF) to align large language models (LLMs) with human values. However, RM training data is commonl…

CLIPO: Contrastive Learning in Policy Optimization Generalizes RLVR

Sijia Cui, Pengyu Cheng, Jiajun Song +6

Reinforcement Learning with Verifiable Rewards (RLVR) has significantly advanced the reasoning capacity of Large Language Models (LLMs). However, RLVR solely relies on final answer…
