Hello, I have made a small Neural Network program in Java. It is base on the simple multiplexer example available at http://alexandria.nu/ai/neural_net_demo/#Use_Demo1 It can do simple tasks as XOR or other binary functions. My intention is to change it so that it can do pattern recognition with non binary inputs. I used Oracle's JDeveloper to develop it. Anyone that is interested can contact me and I will send it. Regards Hans-Peter
