Just to be clear, Minsky didn't need backprop, just the multiple layers. (In order for a perceptron to act like an XOR gate, or to "solve the XOR problem" in some parlance.)
Minsky assumed a trained percepton with the weights already set to act like an AND or an OR gate. He wasn't dealing with the learning problem.
- varjag 10y agoFair point, although without knowing that this approach is practically viable to begin with it was getting into speculations territory. Not that Minsky didn't like to speculate.. Anyway, IMO people overestimate Minsky influence to single-handedly shut down an avenue of research. The reason _Perceptrons_ conclusions caught up is because they were sound and reasonable to his peers at the time. I also seem to remember his video interview from a few years back where he elaborates on perceptrons and how much of his original conclusions are applicable to the state of art ANNs. Can't quite find it though.
- argonaut 10y agoTo reiterate, people already widely knew multiple layers solved XOR at the time.
