cdlib.algorithms.head_tail¶
-
head_tail
(g_original: object, head_tail_ratio: float = 0.4) → cdlib.classes.node_clustering.NodeClustering¶ Identifying homogeneous communities in complex networks by applying head/tail breaks on edge betweenness given its heavy-tailed distribution.
Note: this implementation is suited for small-medium sized graphs, and it may take couple of minutes or longer for a bigger graph.
Parameters: - g_original – a networkx/igraph object
- head_tail_ratio – head/tail division rule. Float in [0,1], dafault 0.4.
Returns: NodeClustering object
Example: >>> from cdlib import algorithms >>> import networkx as nx >>> G = nx.head_tail() >>> coms = algorithms.head_tail(G, head_tail_ratio=0.8)
