  • Artificial Intelligence
OBS

If the extra term (of the error function) is the sum of the squares of the weights, its derivative corresponds to "weight decay" - each weight continually decays towards zero by an amount proportional to its magnitude. When the learning has equilibrated, the magnitude of a weight is equal to its error derivative because this error derivative balances the weight decay.

OBS

See "weight-decay".

Domaine(s)
  • Intelligence artificielle
CONT

Il est naturel de chercher des techniques qui permettent de poursuivre indéfiniment la mémorisation de nouveaux prototypes, quitte à effacer progressivement les plus anciens. L'introduction à cet effet d'un facteur d'oubli dans le mécanisme d'apprentissage avait déjà été proposée.
