Geometric Flow enhanced Graph Coarsening
This study introduces discrete graph curvature, particularly Ollivier-Ricci curvature, as a measure of higher-order connectivity around an edge, and introduces a novel graph pooling method named RicciPool, utilizing the spectral clustering technique to learn a new cluster assignment matrix.
