New theory resolves instability in MeanFlow generative models

Researchers have developed a theoretical framework to address instability issues in MeanFlow training, a one-step generative modeling technique. They identified that the conditional velocity field is misused in the loss function, playing two statistical roles with an incorrect coefficient. The study derives the optimal coefficient, demonstrating that various concurrent fixes are practical implementations of this optimum. Applying this optimized coefficient significantly improves sample quality and leads to a monotonic FID trend in latent Diffusion Transformers. AI
