lais2(g_original: object) → cdlib.classes.node_clustering.NodeClustering

LAIS2 is an overlapping community discovery algorithm based on the density function. In the algorithm considers the density of a group is defined as the average density of the communication exchanges between the actors of the group. LAIS2 IS composed of two procedures LA (Link Aggregate Algorithm) and IS2 (Iterative Scan Algorithm).

Parameters: g_original – a networkx/igraph object NodeClustering object
>>> from cdlib import algorithms
>>> import networkx as nx
>>> G = nx.karate_club_graph()
