DeltaGNN introduces an information flow control mechanism that uses a new connectivity measure, the information flow score, to mitigate over‑smoothing and over‑squashing in Graph Neural Networks. This approach enables linear computational and memory overhead while effectively capturing both short‑range and long‑range node interactions. Experiments on ten diverse real‑world datasets demonstrate superior performance with limited computational complexity.

The paper introduces a Position Encoding-Based Deformable Spatial Aggregation Module (PEBDSAM) that uses a deformable mechanism in position space to identify relevant nodes beyond first‑order neighbors, thereby addressing over‑smoothing, over‑compression, limited receptive fields, and noise from heterophilous graphs. Diagnostic experiments revealed that current offsets are ineffective, yet performance still improves, leading to a streamlined version called PEBSAM and a faster variant, PEBSAM‑Speed. The module is plug‑and‑play and can be integrated into GCN, GAT, GIN, and GraphSAGE, achieving strong results on both homophilous and heterophilous datasets.
