Hi there. I know that this post may be slightly inappropriate for this forum so apologies if it get's anybody's goat. Can anyone point in the direction of any sites that might have have any clustering algorithms already coded in Java? I am trying to code some well-known existing alogrithms in Java and would be grateful just to compare my approach to any that have been previously implemented. Thanks a lot, Joe

You might find something useful in this collection of scientific computing in Java libraries.
The search terms "java data mining cluster" might give you hits that searching for "java clustering" would miss.
If you find anything good, please post the links, this is an area of continuing interest to me.

Hi William. Thnaks for your reply. Unfortunately the link you posted won't open for me. When I click on it a new Web page is generated that simply says "Service Unavailable". Is there anything I need to have installed for me to be able to open it. Cheers, Joe

I had no problems using the link.

The web server may have been down at the moment you tried it. Give it another shot.

I just tried it... and got "Service Unavailable".

I want to back up a bit just to be sure ... define "cluster" in your context. Is it "A computer cluster is a group of loosely coupled computers that work together closely so that in many respects it can be viewed as though it were a single computer?" (taken from http://en.wikipedia.org/wiki/Computer_cluster)

If so there are many aspects of clustering to think about. What parts have you addressed with your own work?

I believe the original question had to do with clustering in the data mining /statistical analysis sense of grouping data items according to their similarity by some measure. Examples appear all the time in the scientific literature: grouping species according to DNA sequence similarity, stars by spectral properties, literary works by word usage.
Amazon does a sort of clustering when it recommends books to you based on your past purchases putting you in a sort of interest cluster.

I still don't have any problem with that link, but a google search for "java data mining cluster" turned up lots of goodies.

It is sorta covered in the JavaRanch Style Guide.
