- Dr. Peter van Beek
Peter van Beek is a Professor in the Cheriton School of Computer Science at the University of Waterloo. He received his PhD in 1990 from the University of Waterloo and at that time joined the faculty at the University of Alberta. Ten years later he returned to Waterloo. His research interests span the field of Artificial Intelligence with a current focus on probabilistic graphical models, constraint programming, and applied machine learning. Peter has co-authored seven research papers which have won awards. From 2005-2009, he served as Editor-in-Chief of the journal Constraints, a forum for research in constraint programming. In 2008, he was named a Fellow of the Association for Artificial Intelligence.
Machine Learning of Bayesian Networks
Bayesian networks are a widely used probabilistic graphical model with diverse applications in knowledge discovery, classification, and decision making. A Bayesian network can either be constructed by a human domain expert or machine learned from data. In this talk, I will review Bayesian networks and their advantages. I will then focus on our recent work on learning the structure of a Bayesian network from discrete data, which has led to improved exact and approximate learning algorithms. Finally, I will briefly present some of our current work on incorporating expert domain knowledge into learning a Bayesian network, and on generating all of the best networks rather than selecting a single network. The talk will be aimed at a general audience.
