Community Detection and the Louvain Method

Community detection is the process of identifying communities within a larger population. The Louvain method is an algorithmic approach that can be used to detect these communities mathematically. The method relies on the concept of modularity, which measures the strength of community connections within a social network graph. By analyzing the edge weights and connections between individuals, the Louvain method calculates a modularity score for each potential community. Communities with higher modularity scores are considered more cohesive and tightly-knit. The method has been successfully applied to large-scale datasets, revealing distinct communities in various domains such as music interests and online social networks.
