HETEROASSOCIATIVE MEMORY [1 record]

Record 1 1992-10-17

English

Subject field(s)
  • Artificial Intelligence
CONT

Pattern Associator. This paradigm is really a variant on the auto-association paradigm. A set of pairs of patterns are repeatedly presented. The system is to learn that when one member of the pair is presented it is supposed to produce the other.

OBS

We can distinguish three types of associative memories: heteroassociative memory, interpolative associative memory, autoassociative memory.

  • Intelligence artificielle
CONT

Il serait plus précis de donner à ce type de mémoire le nom de mémoire autoassociative par opposition aux mémoires hétéroassociatives. Pour ces dernières, le système mémorise p couples de vecteurs et reproduit le (second) vecteur s'il est initialisé avec un vecteur suffisamment proche (du premier).

CONT

Il n'y a pas de réelle différence entre mémoire auto-associative et hétéro-associative. On peut utiliser les réseaux de Hopfield comme mémoire hétéro-associatives.
