cdlib.evaluation.scaled_density

scaled_density(graph: <Mock id='140619399398224'>, communities: object, **kwargs) → object

Scaled density.

The scaled density of a community is defined as the ratio of the community density w.r.t. the complete graph density.

Parameters:
  • graph – a networkx/igraph object
  • communities – NodeClustering object
  • summary – boolean. If True it is returned an aggregated score for the partition is returned, otherwise individual-community ones. Default True.
Returns:

If summary==True a FitnessResult object, otherwise a list of floats.

Example:

>>> from cdlib.algorithms import louvain
>>> from cdlib import evaluation
>>> g = nx.karate_club_graph()
>>> communities = louvain(g)
>>> scd = evaluation.scaled_density(g,communities)
