Abstract
The Helmholtz machine is a new unsupervised learning architecture that uses top-down connections to build probability density models of inpu t and bottom-up connections to build inverses to those models. The wak e-sleep learning algorithm for the machine involves just the purely lo cal delta rule. This paper suggests a number of different varieties of Helmholtz machines, each with its own strengths and weaknesses. and r elates them to cortical information processing.
