En présentant des données dont la réponse attendue est connue à l'avance, il est possible de modifier ses paramètres en favorisant les mises à jour maximisant le nombre de réponses correctes.
L'apprentissage d'un système se base ainsi sur l'architecture d'un modèle, des données et des algorithmes.
Nous pouvons mentionner l'algorithme de descente du gradient qui permet l'apprentissage des paramètres neuronaux.
Mais aussi, l'algorithme de rétropropagation du gradient~[\cite{rumelhart1985learning}], qui rend possible le calcul efficace des gradients d'erreurs.

Nous expliquons davantage le fonctionnement de la descente de gradient dans la prochaine section, puis l'algorithme de rétropropagation dans la section suivante.

Cette méthode de régularisation est aussi appelée Lasso Regession~[\cite{tibshirani1996regression}].
Cette méthode de régularisation est aussi appelée Lasso Regression~[\cite{tibshirani1996regression}].
Il s'agit d'une pénalité appliquée durant l'apprentissage sur la fonction de coût.
Son objectif est de pénaliser les connexions neuronales à forte pondération.
Elles sont responsables d'une plus grande variance des sorties d'un système neuronal~[\cite{geman1992neural}].
