"backprop1" is hosted on Source Forge at http://sourceforge.net/projects/backprop1
I have created some small demonstration programs to validate backprop1. There are demonstrations of point classification (demo1), the XOR problem (demo2) and character recognition (demo3). You might find these useful examples of how backprop1 might be used.
"backprop1" is free for your use. There is no cost, no warranty, no support, nothing but good wishes and java sources. If you do something really neat please send an email about your success. Good luck with your project.
