Random Walks, Conductance, and Resistance for the Connection Graph Laplacian

Alexander Cloninger, Gal Mishne, Andreas Oslandsbotn +3

We investigate the concept of effective resistance in connection graphs, expanding its traditional application from undirected graphs. We propose a robust definition of effective r…

Neural approximation of Wasserstein distance via a universal architecture for symmetric and factorwise group invariant functions

Samantha Chen, Yusu Wang

Learning distance functions between complex objects, such as the Wasserstein distance to compare point sets, is a common goal in machine learning applications. However, functions o…

A generalization of the persistent Laplacian to simplicial maps

Aziz Burak Gülen, Facundo Mémoli, Zhengchao Wan +1

The graph Laplacian is a fundamental object in the analysis of and optimization on graphs. This operator can be extended to a simplicial complex and therefore offers a way to p…

Understanding Oversquashing in GNNs through the Lens of Effective Resistance

Mitchell Black, Zhengchao Wan, Amir Nayyeri +1

Message passing graph neural networks (GNNs) are a popular learning architectures for graph-structured data. However, one problem GNNs experience is oversquashing, where a GNN has…

The Weisfeiler-Lehman Distance: Reinterpretation and Connection with GNNs

Samantha Chen, Sunhyuk Lim, Facundo Mémoli +2

In this paper, we present a novel interpretation of the so-called Weisfeiler-Lehman (WL) distance, introduced by Chen et al. (2022), using concepts from stochastic processes. The W…
