Joseph K. Bradley commented on SPARK-6137:
------------------------------------------
There is a method for splitting clusters in StreamingKMeans. It isn't really
documented, but it's visible in the code:
[https://github.com/apache/spark/blob/e359794cec7d30ece38752f62dc2a1d3d26b8feb/mllib/src/main/scala/org/apache/spark/mllib/clustering/StreamingKMeans.scala#L120].
Do you know how that method relates to GMeans?

> Key: SPARK-6137
> URL: https://issues.apache.org/jira/browse/SPARK-6137
> Project: Spark
> Issue Type: New Feature
> Components: MLlib
> Reporter: Denis Dus
> Priority: Minor
>
> Will it be useful to implement G-Means clustering algorithm based on K-Means?
> G-means is a powerful extension of k-means, which uses test of cluster data
> normality to decide if it necessary to split current cluster into new two.
> It's relative complexity (compared to k-Means) is O(K), where K is maximum
> number of clusters.
> The original paper is by Greg Hamerly and Charles Elkan from University of
> California:
> [http://papers.nips.cc/paper/2526-learning-the-k-in-k-means.pdf]
> I also have a small prototype of this algorithm written in R (if anyone is
> interested in it).
