Restricted Boltzmann Machines

YouTube·Neural Networks

Restricted Boltzmann Machines (RBM) are a particular type of Gibbsian network or graphical model that is distinguished by having a layered structure with a hidden and a visible layer and by the fact that units within a layer are not connected to each other, which makes the units statistically independent given the other layer. RBMs can have many units and are often used to model high dimensional data, such as images.
