We first show that with careful selection of a noise schedule, diffusion models trained over a small number of latent states (i.e. $T \\sim 32$) match the performance of models trained over a much large number of latent states ($T \\sim 1,000$). Second, we push this limit (on the minimum number of latent states required) to a single latent-state, which we refer to as complete disentanglement in T-space. We show that high quality samples can be easily generated by the disentangled model obtained by combining several independently trained single latent-state models. We provide extensive experiments to show that the proposed disentangled model provides 4-6$\\times$ faster convergence measured across a variety of metrics on two different datasets.","short_abstract":"We challenge a fundamental assumption of diffusion models, namely, that a large number of latent-states or time-steps is required for training so that the reverse generative process is close to a Gaussian.
