[pymvpa] Saturation in SOM

[Felipe Duque]

Hello. I've used SOM in MVPA2 for some academic works before and have never
run into any kind of trouble. However, in my most recent work, I'm running
into overflow issues. My input data is [0, 1] normalized.

Delving into som.py code, I'm afraid I didn't notice any kind of
'forgetting' term in the training methods. Is this so? Why is this
saturation taking place?

Thanks
