A hybrid minimizing movement and neural network approach to Willmore flow
Martin Rumpf, Josua Sassen, Christoph Smoch
We present a hybrid method combining a minimizing movement scheme with neural operators for the simulation of phase field-based Willmore flow. The minimizing movement component is…

SDFs from Unoriented Point Clouds using Neural Variational Heat Distances
Samuel Weidemaier, Florine Hartwig, Josua Sassen +3
We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. To this end, we replace the commonly used eikonal equation w…

Entropy-Regularized Optimal Transport in Information Design
Jorge Justiniano, Andreas Kleiner, Benny Moldovanu +2
In this paper, we explore a scenario where a sender provides an information policy and a receiver, upon observing a realization of this policy, decides whether to take a particular…
