ckmeansSSLR: General Interface COP K-Means Algorithm

Description

Model from conclust This function takes an unlabeled dataset and two lists of must-link and cannot-link constraints as input and produce a clustering as output.

Usage

ckmeansSSLR(n_clusters = NULL, mustLink = NULL, cantLink = NULL, max_iter = 10)

Arguments

n_clusters

A number of clusters to be considered. Default is NULL (num classes)

mustLink

A list of must-link constraints. NULL Default, constrints same label

cantLink

A list of cannot-link constraints. NULL Default, constrints with different label

max_iter

maximum iterations in KMeans. Default is 10
