[jira] [Commented] (MAHOUT-1054) Use ball KMeans for clustering
Posted by "Ted Dunning (JIRA)" <ji...@apache.org>.

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.
