DEF

totally connected network having only visible neurons that are cyclically updated until a stable state is obtained

OBS

A Hopfield network has a finite number of stable states, corresponding to local minimums of an energy function. During learning, the connection weights are adjusted so that the stable states correspond to the patterns to be stored. After applying an input pattern, the network evolves toward the closest stored pattern.

OBS

A Hopfield network may be a synchronous neural network or an asynchronous neural network.

OBS

The Hopfield network is mainly used as an associative storage, but has also applications in optimization.

OBS

Hopfield network; crossbar associative network; CAN : terms, abbreviation and definition standardized by ISO/IEC [ISO/IEC 2382-34 : 1999].

DEF

réseau entièrement connecté constitué entièrement de neurones visibles qui sont actualisés cycliquement jusqu'à obtention d'un état stable

OBS

Un réseau de Hopfield possède un nombre fini d'états stables correspondant aux minimums d'une fonction d'énergie. Pendant l'apprentissage, les poids synaptiques sont ajustés de façon que les états stables correspondent aux formes à stocker. Après application d'une forme d'entrée, le réseau évolue vers la forme stockée la plus voisine.

OBS

Un réseau de Hopfield peut être un réseau neuronal synchrone ou un réseau neuronal asynchrone.

OBS

Le réseau de Hopfield sert principalement de mémoire associative, mais trouve aussi des applications en optimisation.

OBS

réseau de Hopfield : terme et définition normalisés par l'ISO/CEI [ISO/IEC 2382-34:1999].

English

Subject field(s)
  • Artificial Intelligence
DEF

A small prototype network in which computers are linked in a crossbar grid of switches.

CONT

A crossbar is a 2-dimensional array of wires linked where they cross via switches. Each of the N computers might be linked to one row and to one column. Or, alternately, a different set of nodes, for example, memories, or/and input-output devices, might be linked at the columns. Thus a crossbar linking N computers has N x N switches.

  • Intelligence artificielle
DEF

Géométrie idéale d'un réseau d'interconnexions qui relie tout le monde à tout le monde. Mais le nombre des liaisons nécessaires croît comme le carré du nombre des processeurs.
