CNF는 시간에 따라 distribution이 어떻게 transform되는지를 보여주고,Score-based model도 SDE로 표현하면 시간에 따라 marginal distribution이 어떻게 변하는지 보여주고, 이는 결국 Fokker-Planck equation인데 Fokker-Planck equation은 SDE의 probability density function이 시간에 따라 어떻게 어떻게 변하는지 를 기술하는 PDE이다. 그리고 special case로, diffusion term이 0이면, Liouville equation이 된다. 그니까flow라는 건, 시간에 따라서 distribution이 transform되는 과정 (probability distribution space에서..

"Every reverse-time diffusion SDE has a corresponding probability flow ODE with the same marginal densities." 그렇다면 DDPM은 diffusion SDE의 discretization이고 DDIM은 probability flow ODE의 discretization인가?

https://arxiv.org/pdf/1810.01367https://github.com/rtqichen/ffjord(ICLR 2019)AbstractA promising class of generative models maps points from a simple distribution to a complex distribution through an invertible neural network. Likelihood-based training of these models requires restricting their architectures to allow cheap computation of Jacobian determinants. Alternatively, the Jacobian trace c..
