UDM-GRPO: Stable and Efficient Group Relative Policy Optimization for Uniform Discrete Diffusion Models
Researchers propose UDM-GRPO, the first framework combining Uniform Discrete Diffusion Models with reinforcement learning for stable training. The method treats final samples as actions and reconstructs diffusion trajectories to align with pretraining distributions, plus introduces efficiency strategies that outperform naive GRPO integration.
