15. Normalizing Flows — Deep Learning for Molecules and Materials
https://dmol.pub/dl/flows.html
Normalizing Flows¶ The VAE was our first example of a generative model that is capable of sampling from \(P(x)\). The VAE has two disadvantages though. The first that you cannot numerically evaluate \(P(x)\), the probability of a single point. The second disadvantage is that training the VAE is difficult, especially because you’re assuming the latent space should be …

Going with the Flow: An Introduction to Normalizing Flows
https://gebob19.github.io/normalizingflows/
What Normalizing Flows DoNormalizing Flows (NFs) (Rezende & Mohamed, 2015) learn an invertible mapping f:X→Zf: X \rightarrow Zf:X→Z, where XXX is our data distribution and ZZZis a chosen latentdistribution. Normalizing Flows are part of the generative model family, which includes Variational Autoenco… Why Normalizing FlowsWith the amazing results shown by VAEs and GANs, why would you want to use Normalizing flows? We list the advantages below Note: Most advantages are from the GLOW paper (Kingma & Dhariwal, 2018) 1. NFs optimize the exact loglikelihood of the data, log(pXp_XpX) 1.1. VAEs …

Sep 21, 2020 · A Normalizing Flow is bijective and applied in one direction for encoding and the other for decoding. That means that you obtain the exact same image after encoding an image into latent space and decoding it again. What are the training objectives of VAE and NF? VAE: Maximize the lower bound of the loglikelihood ( ELBO)

Feb 10, 2019 · Four types of flows are implemented, including two types of general normalizing flows and two types of volumepreserving flows. Planar flow and radial flow are the general normalizing flows proposed in [2]. Householder flow is a volumepreserving flow proposed in [3]. NICE is another volumepreserving flow proposed in [4]. Although characterized as …
