Subject: [alt-beam] Re: Multiple Inputs for Nv neurons
When making more complex Nv/Nu nets, things get a lot tougher. You have
to consider saturation though. If they are not tuned properly, a few
bits of stimuli will put the thing into saturation easily. I believe
Tilden implied that Lobster suffered from this problem in a message he
sent a while back. If you do make large networks with interconnecting
"web like" loops, then be prepared to tune the thing, and be prepared to
spend time on it. A good summer project??? Maybe??? I'd like to see some
new Nv setups.
