Restricted Boltzmann Machine (RBN)

RBMs are a type of probabilistic graphical model that can be interpreted as a stochastic artificial neural network. RBNs learn a representation of the data in an unsupervised manner. An RBN consists of visible and hidden layer, and connections between binary neurons in each of these layers. RBNs can be efficiently trained using Contrastive Divergence, an approximation of gradient descent. • Chapter 6: Information Processing in Dynamical Systems: Foundations of Harmony Theory • An Introduction to Restricted Boltzmann Machines
