perceptron|pəˈsɛptrɒn|
[f. percept n. + -tron.]
A model or machine devised to represent or simulate the ability of the brain to recognize and discriminate, orig. based on statistical concepts.
1958F. Rosenblatt in Psychol. Rev. LXV. 386 (heading) The perceptron: a probabilistic model for information storage and organization in the brain. Ibid. 387/2 The theory has been developed for a hypothetical nervous system, or machine, called a perceptron. The perceptron is designed to illustrate some of the fundamental properties of intelligent systems in general, without becoming enmeshed in the special..conditions which hold for particular biological organisms. 1962W. S. Holmes in G. L. Fischer et al. Optical Character Recognition 213 A program of pattern recognition research based on early concepts of Dr. Frank Rosenblatt..has turned toward the application of perceptrons to useful tasks such as the recognition of printed characters. 1966Y. Bar-Hillel in Automatic Transl. of Lang. (NATO Summer School, Venice 1962) 22 Though certain electronic devices (such as perceptrons) have been built which can be ‘trained’ to perform certain tasks..and though computers have been programmed to do certain things..it would be disastrous to extrapolate from these primitive exhibitions of artificial intelligence to something like translation. 1971New Scientist 2 Sept. 525/2 There are some 50 approaches to neuron modelling and machines were constructed based on some of these models. Perhaps the most famous..was the Perceptron device built at the Cornell Aeronautical Laboratory. 1978A. Bundy et al. Artificial Intelligence v. 184 The important point about a perceptron is that it makes a global decision about a figure by weighing only local evidence. |
