Even though it's very low traffic, the Perl-AI mailing list seems to have some smart people on it:

  http://lists.cpan.org/showlist.cgi?name=perl-ai

My AI::NeuralNet::Simple module has been used successfully by others according to email I've received (http://search.cpan.org/dist/AI-NeuralNet-Simple/).  It's not been maintained because there are no bug reports but that might be because no one is using it any more.

It has an examples/ directory with a couple of smallish programs to give you an idea of how it works.  However, I'm not an AI expert, so the Perl-AI mailing list is a better resource than I.

Cheers,
Ovid
