Louvain¶
-
make_consensus_matrix
(com_membership, th=0.5)[source]¶ Makes the consensus matrix.
From multiple iterations, finds a consensus partition.
- .
- com_membership : array
- Shape should be node, time, iteration.
- th : float
- threshold to cancel noisey edges
- D : array
- consensus matrix
-
make_temporal_consensus
(com_membership)[source]¶ Matches community labels accross time-points.
Jaccard matching is in a greedy fashiong. Matching the largest community at t with the community at t-1.
Parameters: com_membership (array) – Shape should be node, time. Returns: D – temporal consensus matrix using Jaccard distance Return type: array
-
temporal_louvain
(tnet, resolution=1, intersliceweight=1, n_iter=100, negativeedge='ignore', randomseed=None, consensus_threshold=0.5, temporal_consensus=True, njobs=1)[source]¶ Louvain clustering for a temporal network.
Parameters: - tnet (array, dict, TemporalNetwork) – Input network
- resolution (int) – resolution of Louvain clustering ($gamma$)
- intersliceweight (int) – interslice weight of multilayer clustering ($omega$). Must be positive.
- n_iter (int) – Number of iterations to run louvain for
- randomseed (int) – Set for reproduceability
- negativeedge (str) – If there are negative edges, what should be done with them. Options: ‘ignore’ (i.e. set to 0). More options to be added.
- consensus (float (0.5 default)) – When creating consensus matrix to average over number of iterations, keep values when the consensus is this amount.
Returns: communities – node,time array of community assignment
Return type: array (node,time)
