GAMMA: Gated Multi-hop Message Passing for Homophily-Agnostic Node Representation in GNNs

The success of Graph Neural Networks (GNNs) leverages the homophily principle, where connected nodes share similar features and labels. However, this assumption breaks down in heterophilic graphs, where same-class nodes are often distributed across distant neighborhoods rather than immediate connect…
