Witryna29 sty 2024 · Louvain community detection algorithm was originally proposed in 2008 as a fast community unfolding method for large networks. This approach is based on modularity, which tries to maximize the difference between the actual number of edges in a community and the expected number of edges in the community. Witryna23 lis 2024 · The main contributions of this paper are as follows: (1) An improved algorithm based on Louvain is proposed. The algorithm optimizes the iterative logic from the cyclic iteration to dynamic iteration, which speeds up the convergence speed. (2) Split the local tree structure in the network.
Witryna24 mar 2016 · In this work, we modified the original Louvain algorithm [ 1] to fulfill the requirements of a community detection task in evolving large-scale networks. When compared with original Louvain, the proposed modifications revealed to be conclusive about the gains in terms of modularity and speed.
