And if you hold the number of hidden nodes per backprop neuron fixed,
the time it takes per weight update cycle also scales linearly, and
the results are probably about as good as with the Hebb rule. It's
only when you measure the ability of backprop or the Hebb rule to do
something usefull that they scale up poorly. Which makes me confused
about what, if anything, you think your analysis is relevant to.
