Dr. Cory J. Butz
Professor of
Computer Science
at the
University of Regina
in the beautiful city of
Regina, Saskatchewan, Canada

In 2011, he gave invited research seminars at Cambridge and MIT based in part on this work:

The Semantics of Intermediate CPTs in Variable Elimination.

In 2007, he was invited by a Google talent scout to visit Google's Mountain View headquarters in order to discuss an earlier version of the following paper:

A Join Tree Probability Propagation Architecture for Semantic Modeling.

His research primarily focuses on Bayesian networks. Bayesian networks use probability theory as a formal framework for uncertainty management in artificial intelligence.
