Hi John,
Welcome to this community! I am currently completing a new version of Gneural Network that, hopefully, should be soon released. It will be much more advanced than the one that is online right now. In the meanwhile, it would be great if you could have a look to the code that is online (version 0.0.1). Your experience could be VERY useful for this project so it would be great if, after having a look at the source code, you could share your comments and/or ideas! May be you can point us to some method/technique that nobody of us is aware of. In any case, please feel free to share your thoughts!
Best,
JM
