Abstract:
|
A latent Gaussian model is commonly used for restricted Boltzmann machines. The corresponding estimation scheme typically requires calculating the mean and covariance matrix of truncated Gaussian distributions. In this talk, we will present a new efficient algorithm to evaluate probabilities and expectations with respected to a truncated multivariate Gaussian distributions and illustrate its use in the estimation of restricted Boltzmann machines.
