Researchers develop WG-SRC probe to analyze graph neural network behavior

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Researchers have developed WG-SRC, a novel white-box probe designed to analyze and diagnose graph datasets used in graph neural networks. This tool replaces the standard message-passing mechanism with a fixed dictionary of graph signals, enabling a clearer understanding of how nodes are classified. WG-SRC's diagnostics decompose a dataset's behavior into components such as raw features, low-pass propagation, high-pass differences, and class geometry, offering insights for further analysis and dataset modification.

    Operational Feature Fingerprints of Graph Datasets via a White-Box Signal-Subspace Probe

    Graph neural networks achieve strong node-classification accuracy, but their learned message passing entangles ego attributes, neighborhood smoothing, high-pass graph differences, class geometry, and classifier boundaries in an opaque representation. This obscures why a node is c…
