Ben McCann updated MATH-266:
----------------------------
Attachment: clustering.zip
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
http://www.leet.it/home/lale/joomla/component/option,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.
