Researchers have introduced a new method called the predictive divergence mask for improving reinforcement learning in large language models (LLMs). This technique addresses limitations in existing approaches like Proximal Policy Optimization (PPO) and DPPO, which rely on importance ratios that can sometimes conflict with the desired policy updates. The predictive divergence mask aims to better align the direction criterion with the proximity criterion by estimating whether the next policy-gradient step will increase or decrease the probability divergence. This approach has shown improvements in RL training across various model scales and precision settings. AI
