Convolutional deep belief network
In computer science, Convolutional Deep Belief Network (CDBN) is a type of deep artificial neural network that is composed of multiple layers of convolutional restricted Boltzmann machines stacked together.[1] Alternatively, it is a hierarchical generative model for deep learning, which is highly effective in the tasks of image processing and object recognition, though it has been used in other domains too.[2] The salient features of the model include the fact that it scales well to high-dimensional images and is translation-invariant.[3]
CDBNs use the technique of probabilistic max-pooling to reduce the dimensions in higher layers in the network. Training of the network is accomplished in a greedy layer-wise manner, similar to other deep learning networks.
