Generalization error of normalizing flows

WebAll AEs map to latent spaces of dimensionality equal to the number of synthesis parameters (16 or 32). This also implies that the different normalizing flows will have a dimensionality equal to the numbers of parameters. We perform warmup by linearly increasing the latent regularization β from 0 to 1 for 100 epochs. WebThis was published yesterday: Flow Matching for Generative Modeling. TL;DR: We introduce a new simulation-free approach for training Continuous Normalizing Flows, generalizing the probability paths induced by simple diffusion processes. We obtain state-of-the-art on ImageNet in both NLL and FID among competing methods.
