Ollivier's Ricci Curvature on Complex-weighted Graphs
Yu Tian, Eleanor Wiesler, Melanie Weber
Understanding the geometry of complex networks is critical for effective modeling and analysis across domains. While discrete notions of Ricci curvature have emerged as powerful to…

Curvature-based Clustering on Graphs
Yu Tian, Zachary Lubberts, Melanie Weber
Unsupervised node clustering (or community detection) is a classical graph learning task. In this paper, we study algorithms, which exploit the geometry of the graph to identify de…

Forman-Ricci flow for change detection in large dynamic data sets
Melanie Weber, Jürgen Jost, Emil Saucan
We present a viable solution to the challenging question of change detection in complex networks inferred from large dynamic data sets. Building on Forman's discretization of the c…
