arXiv:2508.10651v3 Announce Type: replace Abstract: We present a novel approach for graph classification based on tabularizing graph data via new variants of the Weisfeiler-Leman algorithm and then applying methods for tabular data. The variants are obtained by modifying the underlying logical framework, and we establish a precise theoretical characterization of their expressive power using a novel generalization of the bisimulation game for generalized quantifiers. We then test our method on 14 datasets that span a range of application domains. The experiments demonstrate that on datasets wit

The new Weisfeiler-Leman variants will likely be adopted into standard graph deep learning frameworks, improving model performance on complex relational data.
Enhanced graph classification could accelerate breakthroughs in areas like social network analysis, material science, and personalized medicine, where relationships are paramount.
More generalizable and expressive graph AI might indirectly contribute to the development of more robust and auditable AI systems by better understanding complex dependencies.
