Web2 days ago · Additionally, the graph metrics with the highest contribution in discriminating the four-class problem are nodal degree, transitivity, and nodal efficiency. The nodal degree and efficiency were mostly selected from the alpha band, whereas the transitivity feature was important in the low-delta band. WebTransitivity is the overall probability for the network to have adjacent nodes interconnected, thus revealing the existence of tightly connected communities (or clusters, subgroups, cliques).

WebAn arc-transitive graph, sometimes also called a flag-transitive graph, is a graph whose graph automorphism group acts transitively on its graph arcs (Godsil and Royle 2001, p. 59). More generally, a graph G is called s-arc-transitive (or simply "s-transitive") with s>=1 if it has an s-route and if there is always a graph automorphism of G sending each s-route … WebApr 8, 2024 · Note that this function does not check whether the graph has multi-edges and will return meaningless results for such graphs.
