Greedy modularity maximization
WebOct 18, 2024 · The modularity index (Q) is an important criterion for many community detection heuristics used in network psychometrics and its subareas (e.g., exploratory graph analysis). Some heuristics seek to directly maximize Q, whereas others, such as the walktrap algorithm, only use the modularity index post hoc to determine the number of … WebNov 1, 2024 · Greedy modularity maximization algorithm works basis of the modularity score in which it is an important measure to computes the maximum modularity score from the network. This paper mainly focuses on detecting communities from the benchmark [ 8 ] network and analyzing their structural properties of the network using SNA techniques.
