New descriptor uses tropical geometry for neuronal graph learning

Researchers have developed a novel descriptor for graph learning based on tropical algebraic geometry to analyze 3D neuronal morphologies. This approach aims to overcome the limitations of current message-passing Graph Neural Networks (GNNs) by capturing cycle structures induced by spatial proximities. The proposed method utilizes a structural transformation pipeline and a continuous relaxation on the universal cover of the Albanese torus to compute an Arakelov-Green measure, which provides both node-level structural coordinates and a graph-level signature. This descriptor has shown improved expressivity beyond the 1-Weisfeiler-Lehman test on benchmarks and enhanced classification accuracy on 3D morphology datasets without requiring additional trainable parameters.
