We introduce TopoX, a Python software suite that provides reliable and user-friendly building blocks for computing and machine learning on topological domains that extend graphs: hypergraphs, simplicial, cellular, path and combinatorial complexes.

Weisfeiler and Lehman Go Paths: Learning Topological Features via Path Complexes

no code implementations • 13 Aug 2023 • Quang Truong, Peter Chin

Graph Neural Networks (GNNs), despite achieving remarkable performance across different tasks, are theoretically bounded by the 1-Weisfeiler-Lehman test, resulting in limitations in terms of graph expressivity.
