Web16 Apr 2024 · I ran louvain clustering on a 400x400 correlation matrix (i.e. correlation scores for 400 individuals). When I initially imported my data, my correlation matrix had the same individuals’ ID numbers (i.e. vertex numbers) for both the … WebLouvain maximizes a modularity score for each community. The algorithm optimises the modularity in two elementary phases: (1) local moving of nodes; (2) aggregation of the network. In the local moving phase, individual nodes are moved to the community that yields the largest increase in the quality function.
