@thomaskipf and @wellingmax strike back! in a new blog post w/ @Francesco_dgv @_JRowbottom et al we show that GCN-type models can be derived as gradient flows of Dirichlet-type energy and provably avoid low-frequency dominated dynamics bit.ly/3TdhTLg

This is a super accessible explanation* of our gradient flow work and it's based on a recent arXiv version contanining new theoretical results and experiments *Beware, great meme ahead

What new insights can we gain by leveraging physically-inspired approaches to graph neural networks? Don't miss the latest work from @mmbronstein and coauthors @Francesco_dgv, @b_p_chamberlain, @_JRowbottom, and @thomasmarkovich. buff.ly/3T1cCWU

Looking forward to giving an invited (and in-person!) talk in @jure's group tomorrow @Stanford. I'll talk about our latest take on physics-inspired learning on graphs using non-linear oscillators. arxiv: arxiv.org/abs/2202.02296 code: github.com/tk-rusch/GraphCON w/ @mmbronstein

Graph-Coupled Oscillator Networks

We propose Graph-Coupled Oscillator Networks (GraphCON), a novel framework for deep learning on graphs. It is based on discretizations of a second-order system of ordinary differential equations...

I am happy to share a recent work on energy functionals giving rise to GNN equations via gradient flows 🧵 arxiv.org/abs/2206.10991 This is joint work with @_JRowbottom*, @b_p_chamberlain, T. Markovich, and @mmbronstein

#GNNs are related to PDEs governing information diffusion on graphs. In a new paper with @b_p_chamberlain James Rowbottom @migorinova @stefan_webb @emaros96 we study a new class of Neural Graph Diffusion PDEs Blog post: bit.ly/3gUOEL8 Paper: arxiv.org/abs/2106.10934
