Title: Système et procédé d'entraînement d'un modèle de bruit à l'aide de paires de signaux bruyants
Inventor: MALEKY ALI
IPC: G06T5/00
Filed: 2022-11-15
Abstract: Selon l'invention, un modèle de bruit est entraîné de manière itérative pour simuler l'introduction de bruit par un dispositif de capture, au moyen d'un débruiteur et d'un ensemble de données d'entraînement de paires de signaux bruyants. Des premier et second signaux bruyants de chaque paire sont échantillonnés indépendamment par le dispositif de capture à partir d'informations de source correspondant à la paire. Chaque itération d'entraînement obtient des premier et second signaux débruités à partir de signaux bruyants respectifs, puis optimise au moins une fonction de perte qui additionne des premier et second termes pour entraîner à la fois le modèle de bruit et le débruiteur, le premier terme étant basé sur le premier signal débruité et le second signal bruyant et le second terme étant basé sur le second signal débruité et le premier signal bruyant. L'utilisation d'échantillons bruyants permet d'éviter les complexités de l'obtention de signaux « propres ». En utilisant des fonctions de perte « d'échantillon croisé », la convergence sur des résultats d'entraînement non souhaités est évitée sans régularisation complexe.
