深度信念网络 (Deep Belief Network, DBN) 由 Geoffrey Hinton 在 2006 年提出。它是一种生成模型,通过训练其神经元间的权重,我们可以让整个神经网络按照最大概率来生成训练数据。我们不仅可以使用 DBN 识别特征、分类数据,还可以用它来生成数据。 In this case, the hidden layer of RBM t acts as a visible layer for RBM t+1. However, only a few scientific studies on preserving privacy in deep learning have been conducted. Deep Belief Networks consist of multiple layers, or more concretely, a hierarchy of unsupervised Restricted Boltzmann Machines (RBMs) where the output of each RBM is used as input to the next.
