Abstract

L'invention concerne le domaine des techniques de détection d'une anomalie dans un signal de mesure issu d'un nœud observé Y d'un réseau. Le réseau peut plus particulièrement comprendre une structure arborescente comprenant, outre le nœud observé Y, une pluralité de nœuds non-observés Z , Z ,... Z connecté au nœud observé. L'anomalie à détecter est plus particulièrement susceptible de survenir au niveau des nœuds non-observés. L'invention consiste à exprimer le signal de mesure comme une somme de fonctions adaptatives de variables explicatives, chaque fonction déterminant un comportement attendu du signal de mesure en fonction d'une des variables explicatives et pouvant être adaptée aux observations successives du signal de mesure, pour détecter toute anomalie comme une adaptation d'au moins une des fonctions allant au-delà d'une limite acceptable.The invention relates to the field of techniques for detecting an anomaly in a measurement signal originating from an observed node Y of a network. The network can more particularly comprise a tree structure comprising, in addition to the observed node Y, a plurality of unobserved nodes Z, Z, ... Z connected to the observed node. The anomaly to be detected is more particularly likely to occur in unobserved nodes. The invention consists in expressing the measurement signal as a sum of adaptive functions of explanatory variables, each function determining an expected behavior of the measurement signal as a function of one of the explanatory variables and being able to be adapted to successive observations of the measurement signal, to detect any anomaly such as an adaptation of at least one of the functions going beyond an acceptable limit.
