Path Laplacian Encodings for Directed Graphs

Directed graphs naturally model many real-world systems in which interactions are asymmetric, such as citation networks, web graphs, and information-flow networks. However, graph learning methods commonly rely on message passing with symmetrized graph representations or positional encodings that only partially exploit...

Geometry-Aware Simplicial Message Passing

The Geometric Simplicial Weisfeiler--Lehman (GSWL) test is introduced, which incorporates vertex coordinates into color refinement for geometric simplicial complexes, and shows a clear hierarchy from combinatorial to geometry-aware models.
