Gnn over-squashing
WebJan 29, 2024 · We demonstrate that extending receptive fields via positional encodings and a virtual fully-connected node significantly improves GNN performance and alleviates … WebWe provide a precise description of the over-squashing phenomenon in GNNs and analyze how it arises from bottlenecks in the graph. For this purpose, we introduce a new edge-based combinatorial curvature and prove that negatively curved edges are responsible for the over-squashing issue.

Weblong-distance nodes because of the over-squashing phenomenon (Alon & Yahav, 2024). Another approach is to compute higher-order node-tuple aggregations such as in WL-based GNNs (Maron et al., 2024; Chen et al., 2024); though these models are computationally more expensive to scale than MP-GNNs, even for medium-sized graphs (Dwivedi et al., …
