Outcome Accuracy is Not Enough: Aligning the Reasoning Process of Reward Models

Binghai Wang (Fudan University), Junyang Lin (Alibaba Group)

Reinforcement Learning from Human FeedbackTransformerLarge Language ModelReinforcement LearningPrompt EngineeringTextBenchmarkChain-of-Thought

🎯 What it does: This paper investigates the 'deceptive alignment' problem of reward models (RMs) during the RLHF process, proposes a fine-grained rationale consistency metric, and uses the METAJUDGE framework to perform strict one-to-one semantic matching on model-generated rationales. Subsequently, a hybrid reward combining rationale consistency and outcome accuracy is introduced in the training of the generation reward model (GenRM), proving that the multiplicative form can effectively prevent models from 'cutting corners' based solely on outcome accuracy, ultimately improving the performance of reward models on multiple benchmarks and enhancing the generation quality of RLHF.
