WebLouvain Community Detection Algorithm is a simple method to extract the community structure of a network. This is a heuristic method based on modularity optimization. [1] The algorithm works in 2 steps. WebMar 21, 2024 · Louvain’s algorithm aims at optimizing modularity. Modularity is a score between -0.5 and 1 which indicates the density of edges within communities with respect to edges outside communities [2]. The closer the modularity is to -0.5 implies non modular clustering and the closer it is to 1 implies fully modular clustering.
