Test and training?

Postby MultiD Support » Thu Jul 03, 2008 9:44 am

I have 40 samples in my study. when I run SOM I see only a few symbols dancing around, but when completed I see 40. Whats happening?


I assume you have assigned some samples as test samles. SOM is created based on the training samples only. It's is these that you see dancing around during the training. Once SOM is trained also the test samples are placed in the net.
