I just found that commons-math contains an implementation of a kmeans++ clustering algorithm, but I could not find any documentation on it except for the javadoc. Given the javadoc, I wonder if it is possible to retrieve the actual clusters generated (I.e., sets of the items I input into the algorithm)? I only see that the cluster method returns a list of centroids which would give me the centers, but not the items assigned to each center.
Thanks, Thorsten
