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.
