New GSWL test incorporates geometry into simplicial message passing models

Researchers have developed a new framework called the Geometric Simplicial Weisfeiler--Lehman (GSWL) test to address limitations in existing message passing networks. The GSWL test enhances the Weisfeiler--Lehman (WL) and simplicial extension (SWL) tests by incorporating vertex coordinates, allowing them to distinguish between meshes with identical connectivity but different geometric embeddings. This advancement is expected to improve the expressivity of geometry-aware message passing schemes and has been validated through experiments on synthetic and mesh datasets. AI
