Where: USA
works\ Logical Calculus of the Ideas Immanent in Nervous Activity [1943: with Pitts]; How We Know Universals: the Perception of Visual and Auditory Forms [1947: with Pitts]; What the Frog's Eye Tells the Frog's Brain [1959: with Maturana, Lettvin, and Pitts]
Detail: He lived 1899 to 1972 and studied chimpanzee isocortex. He invented Perceptrons, with Walter H. Pitts. Neuron model sends unit output if input is above threshold. Finite device combinations, including loops, can perform any algorithm. Neural networks can recognize figures, so any input feature from figure produces same output. Reliable neural networks can come from unreliable components using redundancy.
