Researchers have analyzed the training dynamics of MeanFlow, a generative modeling technique that promises high-quality results in few steps. Their analysis reveals that learning the average velocity field is dependent on first establishing the instantaneous velocity field. The study also found that the learning of instantaneous velocity is improved by the average velocity when the temporal gap is small, but this benefit diminishes as the gap widens. Based on these insights, the researchers developed an improved training scheme that accelerates the formation of instantaneous velocity and then shifts focus to average velocities over longer intervals, leading to faster convergence and superior few-step generation performance.
