A new paper published on arXiv introduces a theoretical framework to address the instability issues encountered in MeanFlow training for generative models. The research identifies that the conditional velocity field is misused in the original MeanFlow loss, acting incorrectly as both a regression target and a control variate. The authors derive an optimal coefficient for the control variate role, unifying several concurrent remedies and demonstrating that this variance-optimal coefficient does not always align with the coefficient that yields the best generative quality.
