Well, Kohonen's group at Helsinki University developed the SOMToolBox, which is an excellent implemtation in Matlab of the SOM procedure. You can make LVQ and clustering with this Matlab package, and many others stuffs...
I am trying to develop a Delphi application for classifying images. As I have not enough time to write the code for implementing a SOM LVQ clustering I went around in the www but couldnt find source code for doing the SOM clustering. Please, email me if you know some Delphi or BC++ component, source code or D6 compatible DCU, for doing SOM mapping.
THere is some interesting code at a russian labgroup website, but it is incredibly slow when I run this package. It uses DB files as data source for training the SOM.
Thanks a lot in advance!
