Bucles de entrenamiento personalizados

Personalice bucles de entrenamiento y funciones de pérdida de deep learning

Si la función trainingOptions no proporciona las opciones de entrenamiento que necesita para la tarea, o si las capas de salida personalizadas no son compatibles con las funciones de pérdida que necesita, 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.
