Pave-GRPO enhances generative model alignment via velocity decomposition

Researchers have introduced Pave-GRPO, a novel method to improve the alignment of flow-based generative models with human preferences. This technique reformulates the GRPO objective by decomposing coarse transitions into finer sub-trajectories, allowing reward feedback to reach more intermediate denoising steps. This approach enhances alignment granularity without increasing generation costs, leading to more comprehensive preference optimization and performance improvements across various reward settings.
