Perceptron
The perceptron algorithm was invented in 1958 at the Cornell Aeronautical Laboratory by Frank Rosenblatt , [3] funded by the United States Office of Naval Research . [4] The perceptron was intended to be a machine, rather than a program, and while its first implementation was in software for the IBM 704 , it was subsequently implemented in custom-built hardware as the "Mark 1 perceptron". This machine was designed for image recognition : it had an array of 400 photocells , randomly connected to the "neurons". Weights were encoded in potentiometers , and weight updates during learning were performed by electric motors. [2] : 193 In a 1958 press conference organized by the US Navy, Rosenblatt made statements about the perceptron that caused a heated controversy among the fledgling AI community; based on Rosenblatt's statements, The New York Times reported the perceptron to be "the embryo of an electronic computer that [the Navy] expects will be
