Researchers have introduced ReDiPPO, a novel framework designed to enhance the mathematical reasoning abilities of large language models. This approach addresses the challenge of accurate token-level credit assignment in mathematical tasks, which often have long reasoning chains and sparse rewards. ReDiPPO employs a reference-guided critic that leverages reference answers for more precise value estimation and quantifies discrepancies between standard and reference-guided estimates to reweight token advantages during policy optimization. Experiments show that ReDiPPO surpasses existing methods like PPO, DAPO, and GSPO in mathematical reasoning performance. AI
