This might be slightly off-topic, but I'm curious why you would
consider sigmoid functions as more natural than other non-linearities
in this application. I was of the impression that the most interesting
aspects of sigmoids are to map an unbounded interval to a bounded one
and having nice derivatives which come in handy for neural net
applications. Neither of these seem very relevant for the weakness
to value mapping.
