I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

Hi,

As author and maintainer of AI-NNFlex, I'd like to invite comment, suggestion & feedback in this forum.

I'm currently looking at ways to speed the code up by implementing C or PDL based modules without breaking the flexibility of it.
I'm determined to maintain AI-NNFlex as a resource for implementing neural networks in pure perl, AI-NNFlex will /always/ have full functionality implemented in perl - Inline/xs/pdl functionality will be implemented to provide fast use, but will be faster optional versions of pure perl code.

As per my comments on perlmonks, I'm happy to invite feedback based purely on a review of perldoc, but if posting on that basis please state that this is the case.

Re: Author and maintainer

Hi-

I'm very experienced with perl, and have studied AI as a hobby for many years. A few months ago, I tried your module (with much success) but I did notice that speed was an issue, as you stated. Code optimization is a strength of mine, and I'd like to offer my assistance. I'm looking for a way to give back to the perl community, and this sounds like it'd be a lot of fun.

I already made a number of good mods to the code, but I'll have to dig them up, since I haven't touched it in several weeks.

Thanks,


Jaime

PS - I tried to e-mail you a few weeks ago, using your address listed on cpan, but it didn't go through.

Re: Author and maintainer
Great! Sounds like an opportunity to improve the module and improve my perl. I'd be grateful for any code optimisation you've made to this. I've done a lot of optimisation since the early versions (chiefly getting rid of eval's and unnecessary function calls, and implementing various tricks (courtesy of Scott Fahlman) for speeding up learning) and recent versions are dramatically faster, but you may well have spotted things I've missed.

After something of a hiatus, while I finished off a contract I was working on and finished writing my MSc dissertation, I've got some time to work on this now. Expect a genetic learning module, perhaps a quickprop module, and maybe even a GUI over the next few weeks :-)

The email address listed in the docs should work, but occasionally people have DNS resolution problems with it (sadly, the spammers rarely have a problem). Alternatively you can reach me on colbourn1ATuk2.net, but make sure your subject line references NNFlex, because I spam filter that address rather aggressively. I can also be reached as g0n on perlmonks, and I'm there for at least a couple of hours a day.

thanks,

Charles
