New Diffusion-APO method aligns video diffusion models with user intent

Researchers have introduced Diffusion-APO, a new method for aligning video diffusion models with human preferences. This approach addresses the gap between training noise distributions and real-world inference by synchronizing training noise with denoising paths. Diffusion-APO utilizes a flexible reinforcement learning framework that supports multi-stage alignment without needing scalar rewards, demonstrating superior visual quality and instruction following compared to existing methods.
