Abstract

Procédé et dispositif de détection d'anormalité de données La présente description concerne un procédé de détection d'anomalies utilisant un réseau neuronal artificiel entraîné (502) configuré pour mettre en œuvre au moins une fonction auto-associative destinée à répliquer un échantillon de données d'entrée au niveau d'une ou de plusieurs sorties (A), le procédé comprenant : a) l'injection d'un échantillon de données d'entrée dans le réseau neuronal artificiel entraîné (502) afin de générer un premier échantillon répliqué au niveau desdites une ou plusieurs sorties (A) ; b) l'exécution d'au moins une opération de réinjection ; c) le calcul d'un premier paramètre sur la base d'une distance entre une valeur d'un n-ième échantillon répliqué présent au niveau desdites une ou plusieurs sorties et une valeur d'une des valeurs précédemment injectées ou réinjectées ; et d) la comparaison du premier paramètre avec un premier seuil (), et le traitement de l'échantillon de données d'entrée comme étant un échantillon de données irrégulières si le premier seuil est dépassé.
