Labélisation de signaux
R2026bEffectuez une labellisation manuelle et automatisée des signaux pour entraîner des réseaux d’IA. Labellisez des signaux entiers, des régions d’intérêt ou des points avec des fonctions en ligne de commande ou l’application Signal Labeler. Créez des jeux de signaux labellisés contenant les définitions des données et des étiquettes.
