Abstract
(EN) Disclosed are methods and systems for implementing dynamic control of acoustic fields, which involves the use of machine learning through a Markov Decision Process. The machine learning algorithm monitors an attribute of a system and maintains the attribute within a range by altering a signal sent to an acoustic transducer. The acoustic transducer is configured to alter the attribute of the system. The attribute may be an attribute of the acoustic field produced by the acoustic transducer, or may be an attribute of another element of the system, such as a fluid, a rotor, or a cell mass.
(FR) Sont divulgués des procédés et des systèmes de mise en œuvre d'une commande dynamique de champs acoustiques, qui implique l'utilisation d'un apprentissage automatique par l'intermédiaire d'un processus décisionnel de Markov. L'algorithme d'apprentissage automatique surveille un attribut d'un système et maintient l'attribut dans une plage en modifiant un signal envoyé à un transducteur acoustique. Le transducteur acoustique est configuré pour modifier l'attribut du système. L'attribut peut être un attribut du champ acoustique produit par le transducteur acoustique, ou peut être un attribut d'un autre élément du système, tel qu'un fluide, un rotor ou une masse cellulaire
