Ask HN:Artificial Neural Networks for electronics engineers
paraschopra: All neural networks do is to aggregate input values (which you can model with current) and multiply it by weights (which you can model by variable resistors) and finally output a squished sigmodial output (for which I am sure a circuit must exist). Make elementary units of such neurons and connect them together. Then train the network by manually changing resistors to emulate backpropagation algorithm.Though why you want to do all this through circuits (instead of a computer) is beyond me.
