             Summary: "chooseInitialCenters" should move out from KMeansPlusPlusClusterer
                 Key: MATH-1524
                 URL: https://issues.apache.org/jira/browse/MATH-1524
             Project: Commons Math
          Issue Type: Improvement
            Reporter: Chen Tao


There two reason for "chooseInitialCenters" should be move out from "KMeansPlusPlusClusterer":
# k-means++ clusterer is a special case of k-means clusterer, that k-means++ initialize the cluster centers with k-means++ algorithm. Another case is initialize the cluster centers with random points.
# The mini batch k-means will reuse "chooseInitialCenters".
