Web4 mrt. 2024 · An edgelist is a list of hyper-edges. An incidence matrix is a binary matrix that is hsize (g) x horder (h). A membership vector is the vector of node membership returned from a community detection or clustering algorithm. A hypergraph constructed from a membership vector has a disconnected component for each hyper-edge. WebConstruction of Hypernetwork Hypergraph Graph. In neuroimaging, graph theory as a branch of mathematics has been widely used in brain network analysis, mainly to discretize the brain into different nodes and their interconnection edges (Sporns, 2012; Fornito et …
