Why we should condition denoising diffusion generative models on windows of past observations
Matthias Morzfeld, Daniel Hodyss
Data assimilation (DA) is, traditionally, a cycling process that relies on time-dependent priors to propagate information from past observations to future cycles. Using denoising d…

Using Diffusion Models to do Data Assimilation
Daniel Hodyss, Matthias Morzfeld
The recent surge in machine learning (ML) methods for geophysical modeling has raised the question of how these methods might be applied to data assimilation (DA). We focus on diff…
