(Direct copy-pasta of the abstract) Previous work has shown that the
difficulties in learning deep generative or discriminative models can be
overcome by an initial unsupervised learning step that maps inputs to useful
intermediate representations. We introduce and motivate a new training
principle for unsupervised learning of a represent
