This unit provides an understanding of current methods of automated probabilistic reasoning in graphical models and their application in building expert systems. Techniques for data mining graphical models will also be surveyed. A theoretical background in deterministic and stochastic probability propagation in Bayesian networks is joined with a case study of application development in a domain such as ecological risk assessment or meteorological modeling.


At the completion of this unit students will:

  • be able to design and build probabilistic expert systems;
  • understand the application of probability theory to reasoning under uncertainty;
  • be able to apply automated decision analysis tools;
  • be familiar with the main Bayesian network tools and their capabilities;
  • understand how to data mine graphical models;
  • be able to knowledge engineer Bayesian networks.
