Hi all,
I am on an experiment, for all that knows how Neural Networks works, and if you dont know i give you the link: Neural Networks-Models and algorithms.
A neural network can be emulated by software or hardware.
for hardware, i am going to represent that neuron as opamp configurated as a sum device.
And the weights are represented by resistors,however how can i represent negative values with resistors?. |

That is SOUND interesting...
I never know how analog electronic can represent Neural Network??? 
Then about negative value... I think you can use amplifier better than resistor. Weight is same with amplifier represent on neural network.
Then how you train your network?
The better one is use Digital Electronic or JUST computer.
Good luck.
