K-means clustering is matrix factorization
Webprobabilistic clustering using the Naive Bayes or Gaussian mixture model [1, 9], etc. K-Means produces a cluster set that minimizes the sum of squared errors between the doc-uments and the cluster centers, while both the Naive Bayes and the Gaussian mixture models assign each document to the cluster that provides the maximum likelihood … WebMethod for initialization: ‘k-means++’ : selects initial cluster centroids using sampling based on an empirical probability distribution of the points’ contribution to the overall inertia. This technique speeds up convergence. The algorithm implemented is “greedy k-means++”.
