Weisfeiler-Leman Is Incomplete on Simple Spectrum Graphs, so Canonicalize Them

Snir Hordan, Nadav Dym, Tim Seppelt

Graphs with a simple spectrum admit cubic-time isomorphism testing, yet we prove that for every natural number k, the k-Weisfeiler-Leman (k-WL) test cannot distinguish all no…

When and How to Canonize: A Generalization Perspective

Yonatan Sverdlov, Benjamin Friedman, Snir Hordan +1

While invariant architectures are standard for processing symmetric data, there is growing interest in achieving invariance by applying group averaging or canonization to non-invar…

Quantitative Approximation Rates for Group Equivariant Learning

Jonathan W. Siegel, Snir Hordan, Hannah Lawrence +2

The universal approximation theorem establishes that neural networks can approximate any continuous function on a compact set. Later works in approximation theory provide quantitat…

Spectral Graph Neural Networks are Incomplete on Graphs with a Simple Spectrum

Snir Hordan, Maya Bechler-Speicher, Gur Lifshitz +1

Spectral features are widely incorporated within Graph Neural Networks (GNNs) to improve their expressive power, or their ability to distinguish among non-isomorphic graphs. One po…
