WebJul 17, 2024 · In this blog to understand normalizing flows better, we will cover the algorithm’s theory and implement a flow model in PyTorch. But first, let us flow through the advantages and disadvantages of normalizing flows. Note: If you are not interested in … WebAug 25, 2024 · Normalizing Flows are generative models which produce tractable distributions where both sampling and density evaluation can be efficient and exact. The goal of this survey article is to give a coherent and comprehensive review of the literature around the construction and use of Normalizing Flows for distribution learning.
WebI think that for most applications of normalizing flows (latent structure, sampling, etc.), GANs and VAEs are generally superior at the moment on image-based data, but the normalizing flow field is still in relative infancy.
WebMar 5, 2024 · I saw a talk from CMU on normalizing flows and the guy's point was that they are not really great at generating good quality samples. The analysis of these models is possible due to the dynamics of the algorithm and the nature of layers.
