Self Organizing Map (SOM) Implementation

Question

I'm looking for a C, C++ or Java based SOM implementation with licensing applicable for commercial use (non-zero cost is okay).

So far I'm aware that there exists SOM_PAK (from Kohonen), but the licensing forbids commercial use.

Is anyone aware of alternative implementations?

How about this, it's BSD licensed.

+1 - thanks for paying attention to my language and license request -- this looks great. For others reading this question/answer, there's also a Java version by the same guys here: jknnl.sourceforge.net – Canaille

Hi, do you know how to run it with big data set? Private computer can not handle such big data set. – Busse
