Researchers have introduced a new paradigm called "Think Before You Score" for evaluating visual generation models. This approach, embodied by the Thinking Reward Model (TRM), focuses on creating case-adaptive rubrics and performing rubric-guided assessments to generate fine-grained, pointwise rewards. To address potential score polarization issues with traditional methods, they also developed Pairwise Dual-Group Relative Policy Optimization (PD-GRPO). Experiments show TRM outperforms other open-source reward models and competes with proprietary ones, effectively improving visual generation models when used as a reward signal in reinforcement learning.
