Superiority of GNN Over NN in Generalizing Bandlimited Functions
Superiority of GNN Over NN in Generalizing Bandlimited Functions
Graph Neural Network (GNN) with its ability to integrate graph information has been widely used for data analyses. However, the expressive power of GNN has only been studied for graph-level tasks but not for node-level tasks, such as node classification, where one tries to interpolate missing nodal labels from the …
