Hmm, even tough I've validated my BP algorithm with JavaNNS, a neural net doesn't always achieve a result when training XOR. Is this a documented symptom?
If I place the same value on all weights, it doesn't seem to reach a solution. Seemingly, I would venture, the net enjoys more success when filled with random weights that favor a certain result. I'm off for holidays, but I will post more results here when I have them. Thanks all, and to all happy holidays with your families.
