Entrenamiento personalizado mediante diferenciación automática
Si la función trainingOptions no proporciona las opciones de entrenamiento que necesita para la tarea o tiene una función de pérdida que la función trainnet no admite, puede definir un bucle de entrenamiento personalizado. Para los modelos que no se pueden especificar como redes de capas, puede definir el modelo como una función. Para obtener más información, consulte Define Custom Training Loops, Loss Functions, and Networks.
