Chen Tao updated MATH-1524:
---------------------------
Description:
There are 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".
