New framework analyzes MPNN expressivity across graph sizes

By PulseAugur Editorial · [1 sources] ·

A new theoretical framework has been developed to analyze the expressive power of random-feature Message Passing Neural Networks (MPNNs) across varying graph sizes. This framework demonstrates that while continuous random features enhance MPNN expressivity, these networks are not universally size-uniform. The research also establishes that random-color MPNNs are incomparable to higher-order Weisfeiler-Leman methods and presents constructions for specific graph tasks. AI

IMPACT Provides a theoretical foundation for understanding the capabilities and limitations of MPNNs in graph-based machine learning tasks.

    The Expressive Power of Random-Feature MPNNs Across Graph Sizes

    arXiv:2610.12809v1 Announce Type: new Abstract: Continuous random node features increase the expressivity of message-passing neural networks (MPNNs), but existing theoretical analyses are not fine-grained enough to capture their limitations, particularly in approximating function…
