HyperEF: Spectral Hypergraph Coarsening by Effective-Resistance Clustering

1 code implementation26 Oct 2022 Ali Aghdaei, Zhuo Feng

This paper introduces a scalable algorithmic framework (HyperEF) for spectral coarsening (decomposition) of large-scale hypergraphs by exploiting hyperedge effective resistances.

HyperSF: Spectral Hypergraph Coarsening via Flow-based Local Clustering

1 code implementation17 Aug 2021 Ali Aghdaei, Zhiqiang Zhao, Zhuo Feng

To address the ever-increasing computational challenges, graph coarsening can be potentially applied for preprocessing a given hypergraph by aggressively aggregating its vertices (nodes).
