The Louvain method for community detection is a method to extract communities from large networks created by Blondel et al. from the University of Louvain (the source of this method's name). The method is a greedy optimization method that appears to run in time See more The inspiration for this method of community detection is the optimization of modularity as the algorithm progresses. Modularity is a scale value between −0.5 (non-modular clustering) and 1 (fully modular clustering) … See more The value to be optimized is modularity, defined as a value in the range $${\displaystyle [-1/2,1]}$$ that measures the density of links inside communities compared to links between communities. For a weighted graph, modularity is defined as: See more • Modularity (networks) • Community structure • Network science See more • Twitter social Network (2.4 Million nodes, 38 million links) by Josep Pujol, Vijay Erramilli, and Pablo Rodriguez: The authors explore the … See more When comparing modularity optimization methods, the two measures of importance are the speed and the resulting modularity value.
