Subject [jira] Updated: (MATH-266) Support for Clustering Algorithms
Date Fri, 01 May 2009 23:15:30 GMT


Ben McCann updated MATH-266:


Here's an implementation of the k-means++ clustering algorithm.
I tested it out by using it for image segmentation and it worked well (reducing # of colors
in image by clustering on pixel values - for an example see,com_wrapper/Itemid,50/).
 It was much much faster than Rafael Santos's library which I ran as a comparison.  If all
looks good and this is committed, then I'll follow up shortly by submitting some unit tests
for it.
