GCNH: A Simple Method For Representation Learning On Heterophilous Graphs

Andrea Cavallo, Claas Grohnfeldt, Michele Russo +2

Graph Neural Networks (GNNs) are well-suited for learning on homophilous graphs, i.e., graphs in which edges tend to connect nodes of the same type. Yet, achievement of consistent…
