-------------------------------------

Hi, I would like to work on this issue. How do I get assigned to this?

> 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).
