Abstract: In this talk, we'll introduce denoising diffusion models, a class of generative models that rely on additive Gaussian white noise denoising. We'll explain the link with particule based method of the heat equation in high-dimension. We'll apply these techniques to numerical of multi-layer QG equation in a double-gyre setting, which is an idealized model of the north-atlantic ocean with a western-boundary (gulf-stream like) current, viewing the numerical solutions of QG equations as a stochastic process that we learn without using explicitly physical priors.
