WebNormalizing flow (NF) is a type of invertible neural network (INN) containing a series of invertible layers, which aims to learn a probability distribution (e.g. cat images). After training, NF can output a white noise image given an input as a cat image in the distribution. Thanks to its invertibility, we can easily draw sample images from the ...

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. WebAlthough we now know how a normalizing flow obtains its likelihood, it might not be clear what a normalizing flow does intuitively. For this, we should look from the inverse perspective of the flow starting with the …
