Dr. Cory J. Butz

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.

He received the 2014 University of Regina Alumni Association Award for Excellence in Teaching.

He is a co-founder of Darwinian networks.

Graduate Student Supervision

- Getting ready to give a seminar at the University of Saskatchewan on research findings obtained with two of my students, Mr. Jhonatan Oliveira and Mr. Andre dos Santos.
- After the seminar, discussing the feedback and future papers with Jhonatan (front) and Andre (back). (It was -30C outside in Saskatoon.)
- Discussing research with Jhonatan and Andre in Brazil in 2014. (Much warmer, and why am I in a suit?)
