[...] una RBM [máquina de Boltzmann restringida] por sí sola está limitada en cuanto a lo que puede representar. Su verdadero poder se ve cuando se usan "apiladas" para formar una red de creencia profunda [...], un modelo generativo de varias capas. Aquí, cada capa contiene un conjunto de unidades binarias o con valores continuos, y están conectadas con todas las unidades de las capas adyacentes pero no entre las de una misma capa. A esta pila se le agrega una capa final que mapeará la última capa oculta con las unidades de salida.
