Discovering Structure in High-Dimensional Data Through Correlation Explanation
We introduce a method to learn a hierarchy of successively more abstract representations of complex data based on optimizing an information-theoretic objective. Intuitively, the optimization searches for a set of latent factors that best explain the correlations in the data as measured by multivariate mutual information. The method is unsupervised, requires no model assumptions, and scales linearly with the number of variables which makes it an attractive approach for very high dimensional systems. We demonstrate that Correlation Explanation (CorEx) automatically discovers meaningful structure for data from diverse sources including personality tests, DNA, and human language.

Discovering Structure in Continuous Variables Using Bayesian Networks
Hofmann, Reimar, Tresp, Volker
We study Bayesian networks for continuous variables using nonlinear conditionaldensity estimators. We demonstrate that useful structures can be extracted from a data set in a self-organized way and we present sampling techniques for belief update based on Markov blanket conditional density models. 1 Introduction One of the strongest types of information that can be learned about an unknown process is the discovery of dependencies and -even more important-of independencies. Asuperior example is medical epidemiology where the goal is to find the causes of a disease and exclude factors which are irrelevant.

Discovering Structure from Motion in Monkey, Man and Machine
DISCOVERING STRUCfURE FROM MOTION IN MONKEY, MAN AND MACHINE Ralph M. Siegel· The Salk Institute of Biology, La Jolla, Ca. 92037 ABSTRACT The ability to obtain three-dimensional structure from visual motion is important for survival of human and nonhuman primates. Using a parallel processing model, the current work explores how the biological visual system might solve this problem and how the neurophysiologist might go about understanding the solution. In the present work, much effort has been expended mimicking the visual system. This was done for one main reason: the model was designed to help direct physiological experiments in the primate. It was hoped that if an approach for understanding the model could be developed, the approach could then be directed at the primate's visual system.
