New algorithms efficiently explain graph neural network decisions

Researchers have developed new algorithms to efficiently explain the decision-making processes of graph neural networks (GNNs). These methods, based on message passing techniques, significantly reduce the computational complexity of higher-order attribution schemes like GNN-LRP. The new algorithms can attribute subgraphs in linear time relative to network depth, offering a scalable and useful approach for understanding how GNNs utilize features and neighboring graph information.
