[jira] [Commented] (MAHOUT-1054) Use ball KMeans for clustering

    [ https://issues.apache.org/jira/browse/MAHOUT-1054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13432896#comment-13432896 ] 

Ted Dunning commented on MAHOUT-1054:
-------------------------------------

See https://github.com/tdunning/knn/blob/master/src/main/java/org/apache/mahout/knn/cluster/BallKmeans.java

for reference.  I intend to bring this in during the 0.8 process.

Pulling the code in early is fine by me, but the current knn stuff has some serious deficiencies in that it doesn't yet implement the Mahout standard for clustering algorithms, nor does it have a map-reduce implementation.  The ball k-means is also currently untested.
