Local-Global Geometric Insights for Graph Neural Networks via Entropic Curvature

Rachid Caich, Yassine Abbahaddou

Curvature notions on graphs, particularly Ollivier-Ricci and Forman, have emerged as powerful tools for addressing fundamental issues in Graph Neural Networks (GNNs) such as oversmoothing and oversquashing, but rely almost exclusively on local edge-level comparisons and therefore…Read more
