Capas personalizadas

Defina capas personalizadas de deep learning

Para la mayor parte de las tareas, puede usar capas integradas. Si no hay una capa integrada que necesita para la tarea, puede definir su propia capa personalizada. Puede definir capas personalizadas con parámetros que se puedan aprender y de estado. Después de definir una capa personalizada, puede comprobar que es válida y compatible con la GPU, y que devuelve como salida gradientes correctamente definidos. Para obtener una lista de capas compatibles, consulte Lista de capas de deep learning.
