WebOct 5, 2024 · We introduce a novel “Poisson flow” generative model (PFGM) that takes advantage of a surprising physics fact that extends to N dimensions. They interpret N-dimensional data items x (say, pictures) as positive electric charges in the z = 0 plane of an N+1-dimensional environment filled with a viscous liquid like honey. As shown in the ... http://arxiv-export3.library.cornell.edu/abs/2302.04265
WebSep 22, 2024 · Experimentally, PFGM achieves current state-of-the-art performance among the normalizing flow models on CIFAR-10, with an Inception score of $9.68$ and a FID … WebAbstract. We propose a new "Poisson flow" generative model~ (PFGM) that maps a uniform distribution on a high-dimensional hemisphere into any data distribution. We interpret the data points as electrical charges on the z = 0 z = 0 hyperplane in a space augmented with an additional dimension z z, generating a high-dimensional electric field (the ...
Webto the Poisson’s equation with the data as sources). We will interchangeably refer to this gradient as the Poisson field, since electric fields normally refer to the special case N = 3. The proposed generative model PFGM has a stable training objective and empirically outperforms previously state-of-the-art continuous flow methods [30, 33].
