Research:Revision scoring as a service/Clustering in reverted edits

This is result of clustering using K-means algorithm. Code is here. First number is number of reverted edits, second one is coordinate of cluster centers (note that these features are scaled and normalized). The third one is cost function per number of clusters and last one is difference between them.

Note that Turkish Wikipedia and Indonesian Wikipedia have features with zero variance which needs investigation.
