If we denote g0 = x, the generative model for the rst layer P(xjg1)also follows (1). 2.1 Restricted Boltzmann machines The top-level prior P(g‘ 1;g‘) is a Restricted Boltzmann Machine (RBM) between layer ‘ 1 and layer ‘. To lighten notation, consider a generic RBM with input layer activations v (for visi- • The difference between the Stacked Restricted Boltzmann Machines and RBM is that RBM has lateral connections within a layer that are prohibited to make analysis tractable. On the other hand, the Stacked Boltzmann consists of a combination of an unsupervised three-layer network with symmetric weights and a supervised fine-tuned top layer for recognizing three classes. • The usage of Stacked Boltzmann is to understand Natural languages, retrieve documents, image gen…
