New GPU method scales graph neural network expressiveness analysis to massive graphs
Researchers have developed a new method to analyze the expressiveness of graph neural networks (GNNs) by scaling Weisfeiler-Leman (1-WL) stable coloring computations to massive graphs. Their approach utilizes a linear-a…

New PRiSM method offers complete graph canonicalization for GNNs
Researchers have demonstrated that the Weisfeiler-Leman (WL) test, a common method for graph isomorphism testing, is incomplete for graphs with simple spectra. This limitation extends to Graph Neural Networks (GNNs) tha…
