>>During my 20 years working on artificial neural networks I have become
more and more convince that they have very little similarity to the
real neural networks in the brain. I'm not aware of any biological
equivalent to the weights and bias in an artificial neuron. If such
weights exist then I would suggest that they are set and adjusted by
the local release of neuro-chemicals rather than by some action
similar to back propagation in artificial neural networks.
