Researchers have introduced a new structural edge feature for Graph Neural Networks (GNNs) called edge-girth. This feature, which captures the length and multiplicity of the shortest cycle passing through an edge, aims to overcome the limitations of traditional GNNs that are no more powerful than the Weisfeiler-Leman color-refinement test. When integrated into a gated message-passing architecture (EGAGNN), edge-girth demonstrated a significant reduction in test Mean Absolute Error on the ZINC-12k regression benchmark. However, the descriptor has limitations, as it can become constant in certain graph structures, causing models built upon it to revert to the 1-WL bound and fail to distinguish specific graph pairs.
