History of Neural Networks Research
1943 McCulloch & Pitts model of neuron.
ni(t+1) = ? (? j wij nj(t) - ?i), ?(x) = 1 if x ? 0;
1962 Frank Rosenblatt’s book gives a training algorithm for finding the weights wij from examples.
1969 Marvin Minsky and Seymour Papert publish Perceptrons, and prove that 1-layer perceptrons are incapable of computing image connectedness.
1974-89, 1982: Associated content-addressable memory.
Backpropagation: Werbos 1974, Parker 1985, Rumelhart, Hinton, & Williams 1986.
