Details: architecture based on PerceiverIO. We pre-trained GReAT on MedShapeNet with Laplacian-based supervision target. We found that the learned represenation benefits wall shear stress assessment in a small dataset of coronary arteries. Published in proceedings of ShapeMI (MICCAI) 2025.

cheers for the tip!

We propose a time-efficient surrogate model for the extrapolation of transient fluid dynamics from a steady-state flow and pressure field in coronary arteries. Like all neural operators, the model learns a discretisation-independent map between (infinite-dimensional) function spaces.

If you are excited about representation learning, point clouds, higher-order complexes, or just curious about geometry/topology, this talk is for you!

I also found out that William Kingdon Clifford (after whom Clifford algebra is named) is buried in London, so I visited his grave to pay respects.

...and to the organisers (including @simofoti.bsky.social, @valegiunca.bsky.social, @daniel-platt.bsky.social and @pragya-singh.bsky.social) for this great opportunity.

Special thanks to my committee @erikjbekkers.bsky.social, Oscar Camara, Remco Duits, Bernard Geurts, Michel Versluis, and Jolanda Wentzel, my paranymphs @dieuwertjea.bsky.social and Patryk Rygiel and of course my supervisors @jelmerwolterink.bsky.social and @christophbrune.bsky.social!
