Title
(EN) METHOD AND SYSTEM FOR GENERATING EMBEDDING FOR SIGNAL
(FR) PROCÉDÉ ET SYSTÈME DE GÉNÉRATION D'INTÉGRATION POUR SIGNAL
Abstract
(EN)
A method for generating an embedding for a signal, which is invariant to an operator, by first measuring the signal with each vector from a set of measurement vectors to produce a corresponding set of coefficients, wherein the measuring compares and transforms each measurement vector and the signal using the operator. A set of one or more matching coefficients according to predefined criteria are selected. Then, the matching coefficients are combined to produce the embedding for the signal, wherein the embedding is operator invariant.
(FR)
L'invention également un procédé permettant de générer une intégration pour un signal, qui est invariante par rapport à un opérateur, en mesurant d'abord le signal avec chaque vecteur à partir d'un ensemble de vecteurs de mesure pour produire un ensemble correspondant de coefficients, la mesure comparant et transformant chaque vecteur de mesure et le signal à l'aide de l'opérateur. Un ensemble d'un ou plusieurs coefficients de mise en correspondance conformément à des critères prédéfinis sont sélectionnés. Ensuite, les coefficients de mise en correspondance sont combinés pour produire l'intégration pour le signal, l'intégration étant invariant d'opérateur.
