Thx ApochPiQ,


I've done exactly that, capture a 400x400 area and reduce to 100x100, but the results are simply not acceptable.


What alternative are there outside of the outdated win32 gdi api?



In Topic: Backpropagation XOR issue

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.

I think I found something wrong with my code, I'm using JavaNNS to validate it right now, if I still have issues, I'll post them here soon.


For now thank you for your patience and assistance. smile.png

Sure, ok, I think I can do that. Gimme a day and I'll post the results... brb....

So, you believe I should run the back-propagation always, period. Ok, I will change the code to do that.


Do you think sharing the weights after a run, and after, say, 100 runs, here, would be useful?


Thank you!
