582—Bayesian Networks and Decision Graphs [=CSCE 582] (3) (CSCE 350; STAT 509 or STAT 515) Normative approaches to uncertainty in artificial intelligence. Probabilistic and causal modeling with Bayesian networks and influence diagrams. Applications in decision analysis and support. Algorithms for probability update in graphical models.
Course Homepage: Recent Semester
Usually Offered: Irregularly, once every two years, in the Computer Science Department
Purpose: To appreciate the foundations, power, and limitations of probabilistic and causal modeling with Bayesian networks, solve computer-based decision analysis problems using a Bayesian network and influence diagram tool, and understand and implement structure-based (non-iterative) algorithms for probability update in graphical models.
