New research questions data augmentation's role in diffusion model training

Researchers explored the effectiveness of representation alignment in accelerating diffusion transformer training and enhancing generation quality. They investigated the mechanism behind improvements from SRA to Self-Flow, specifically the dual-time scheduling, and proposed that the gains might stem from data augmentation rather than token interactions across noise levels. Through an experiment called Attention Separation, which blocks attention between tokens at different noise levels while maintaining dual-timestep input, they found that removing these interactions did not harm performance and could even improve it. This suggests that data augmentation along the noise dimension is the primary driver of improvement, and Attention Separation itself acts as an augmentation method by splitting images into effective training parts.

    From SRA to Self-Flow: Data Augmentation or Self-Supervision?

    Representation alignment has become an effective way to accelerate diffusion transformer training and improve generation quality. Recent self-alignment methods, such as SRA and Self-Flow, further remove the dependency on external pretrained encoders by constructing alignment with…
