Researchers have introduced Structured Role-aware Policy Optimization (SRPO), a novel method to enhance the reasoning abilities of large vision-language models (LVLMs). SRPO addresses the limitation of current reinforcement learning techniques by assigning credit at the token level, distinguishing between tokens responsible for visual perception and those for deriving answers. This approach refines existing Group Relative Policy Optimization (GRPO) by using self-distilled contrasts to emphasize role-specific signals, thereby improving evidence-grounded reasoning without external reward models.
