NETWORK CLUSTERING BY ADVANCED LABEL PROPAGATION ALGORITHM

Krista Rizman Žalik, Borut Žalik

Abstract

Real time community detection is enabled by recently proposed linear time – O(m) on a network with m edges – label propagation algorithm (LPA). LPA finds only local maxima in modularity space. To escape local maxima, we propose LPA* that propagate label of a neighbour node having the most common neighbours in the case when multiple neighbour labels are equally frequent and use multistep try of propagation of each neighbour label in the case when multiple neighbour labels are equally frequent in two successive iterations. Experiments show that LPA* detects communities with high modularity values. LPA* propagation is more stable and improves detection of natural communities while it retains high scalability and simplicity of label propagation.
