Fondamentaux de la génération de code pour le Deep Learning
Vous pouvez utiliser MATLAB® Coder™ avec Deep Learning Toolbox™ pour générer du code C++ à partir d’un CNN (réseau de neurones à convolution) entraîné. Vous pouvez ensuite déployer le code généré sur une plateforme embarquée utilisant un processeur Intel® ou ARM®. Il est également possible de générer du code C ou C++ à partir d’un CNN entraîné ne dépendant pas de bibliothèques tierces.
