Web8 jan. 2024 · In this article, we present a simple yet effective semi-supervised node classification method named Hypergraph Convolution on Nodes-Hyperedges network, which performs filtering on both nodes and hyperedges as well as recovers the original hypergraph with the least information loss. WebWe contruct hypergraph random walks utilizing optional “edge-dependent vertex weights”, which are weights associated with each vertex-hyperedge pair (i.e. cell weights on the incidence matrix). The probability transition matrix of this random walk is used to construct a normalized Laplacian matrix for the hypergraph.
