Check out this work led by my student Brandon Zhao (@joiedeposter), with @pratul, @dorverbin, @jon_barron & Y. Wang! We use trainable pyramids to solve PDEs more accurately. I even got to learn a little about PDEs along the way - handy now that they seem to be all over the news!
Introducing beignet, a new neural field architecture!
beignet uses a multiresolution fourier frequency pyramid to achieve faster convergence and higher precision when solving PDEs and finding singularities.
Teaser: here is beignet at work fitting an image (super fast)!

Recent results on unstable fluid singularities point toward harder open questions, including unforced Navier–Stokes (e.g. arxiv.org/abs/2509.14185). Burgers' is a much simpler PDE, but we think beignet might be an important building block towards something bigger!
