Effective Structural Encodings via Local Curvature Profiles

1 code implementation24 Nov 2023 Lukas Fesser, Melanie Weber

We further show that combining local structural encodings, such as LCP, with global positional encodings improves downstream performance, suggesting that they capture complementary geometric information.

Mitigating Over-Smoothing and Over-Squashing using Augmentations of Forman-Ricci Curvature

1 code implementation17 Sep 2023 Lukas Fesser, Melanie Weber

Several rewiring approaches utilizing graph characteristics, such as curvature or the spectrum of the graph Laplacian, have been proposed.

Understanding and Mitigating Extrapolation Failures in Physics-Informed Neural Networks

1 code implementation15 Jun 2023 Lukas Fesser, Luca D'Amico-Wong, Richard Qiu

Physics-informed Neural Networks (PINNs) have recently gained popularity due to their effective approximation of partial differential equations (PDEs) using deep neural networks (DNNs).
