International Encyclopedia of Systems and Cybernetics

2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access.

About

The International Encyclopedia of Systems and Cybernetics was first edited and published by the system scientist Charles François in 1997. The online version that is provided here was based on the 2nd edition in 2004. It was uploaded and gifted to the center by ASC president Michael Lissack in 2019; the BCSSS purchased the rights for the re-publication of this volume in 200?. In 2018, the original editor expressed his wish to pass on the stewardship over the maintenance and further development of the encyclopedia to the Bertalanffy Center. In the future, the BCSSS seeks to further develop the encyclopedia by open collaboration within the systems sciences. Until the center has found and been able to implement an adequate technical solution for this, the static website is made accessible for the benefit of public scholarship and education.

NETWORK (Hopfield) 2)

← Back

For a good introductory graphical description of this network, see P. DENNING (1992b, p.427 -8).

HOPFIELD introduces nonlinear dynamics in computational networks. In DENNING's words: "HOPFIELD showed that his network can memorize patterns by storing them directly into the weights; no training is needed. There is a feedback path from the output of each unit to the input of every other unit, and all of these paths are assigned individual weights… Ultimately the network settles into a condition of equilibrium… If an input pattern does not exactly match one of the memorized patterns, the network will reach equilibrium at the nearest memorized pattern. This behavior provides a means for restoring a pattern from a noisy or a partial version" (Ibid).

HOPFIELD's networks are somehow reminiscent of ASHBY's homeostat.
