When Do Graph Neural Networks Help with Node Classification? Investigating the Homophily Principle on Node Distinguishability
NeurIPS 2023poster
Homophily principle, i.e., nodes with the same labels are more likely to be connected, has been believed to be the main reason for the performance superiority of Graph Neural Networks (GNNs) over Neural Networks on node classification tasks. Recent research suggests that, even in the absence of homo…
