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 ...
