How Spatial Heterophily Improves Urban Graph Neural Networks

Urban graphs often exhibit spatial heterophily, where neighboring nodes differ significantly, limiting traditional GNNs; this article introduces a Spatial Heterophily Aware GNN (SHGNN) that partitions neighborhoods by geographic proximity, employs rotation‑scaling aggregation and heterophily‑sensitive interaction, and demonstrates superior performance on three real city datasets.
