An Efficient Learning Procedure for Deep Boltzmann Machines
(2010-08-04)We present a new learning algorithm for Boltzmann Machines that contain many layers of hidden variables. Data-dependent statistics are estimated using a variational approximation that tends to focus on a single mode, and ...

(Semi-)Predictive Discretization During Model Selection
(2003-02-25)In this paper, we present an approach to discretizing multivariate continuous data while learning the structure of a graphical model. We derive the joint scoring function from the principle of predictive accuracy, which ...
