POLIA: Policy Optimization with Visual-Object-Level Intrinsic Advantage for Multimodal Reasoning

Recent advances in group-based reinforcement learning (RL) greatly improve LLMs' ability in text reasoning. Yet, these methods lack sufficient modeling of multimodal information, leading to significant reasoning hallucination. In this work, we propose POLIA, a novel group-based RL method with visual…
