Stochastic Gradient Estimate Variance in Contrastive Divergence and Persistent Contrastive Divergence

20 Dec 2013Mathias BerglundTapani Raiko

Contrastive Divergence (CD) and Persistent Contrastive Divergence (PCD) are popular methods for training the weights of Restricted Boltzmann Machines. However, both methods use an approximate method for sampling from the model distribution... (read more)
