Blondel, Jean-Loup Guillaume, Renaud Lambiotte In this paper, in Section 2, we first illustrate the original Louvain algorithm and the shortcoming of the Random Neighbor Louvain algorithm. In most real-world networks, the nodes/vertices tend to be organized into tightly-knit modules known as communities or clusters, such that nodes within a community are more likely to be "related" to one Although community detection in networks has been studied for many years, a high-speed and high-quality community detection algorithm is Community detection (or clustering) in large-scale graphs is an important problem in graph mining. developed the algorithm – finds communities by optimizing modularity locally for every node’s neighborhood, then louvain_communities # louvain_communities(G, weight='weight', resolution=1, threshold=1e-07, max_level=None, seed=None) [source] # Find the best partition of a graph using the Louvain Specification and use cases for the Louvain community detection algorithm.
