Introduction & Motivation Slides ...
Class Objectives and Content
This course is a thorough introduction to one of the most important and
central classes of methods in presentday Artificial Intelligence.
It will introduce students to the basic concepts of
Probabilistic Graphical Models as representations of uncertain knowledge
in complex domains. All three aspects related to such models will be covered:
model semantics, inference, and learning.
In particular, the following topics will be covered (in more or less detail):
 Elementary Concepts:
Basics on Probability Distributions, Density Functions,
Probabilistic Reasoning and Inference.
 Bayesian Networks:
Representation, Semantics, Conditional Independence, Factorisation.
 Inference in Bayesian Networks:
Exact Inference, Variable Elimination Algorithms;
Approximate Inference via Stochastic Sampling,
Markov Chain Monte Carlo (MCMC) Methods.
 Learning Bayesian Networks:
Parameter Learning, Structure Learning, Learning Generative vs. Discriminative Models.
 Modelling and Reasoning about Temporal Phenomena:
Kalman Filters, Hidden Markov Models, Dynamic Bayes Nets.
 (Briefly, if there is time:) Semidirected and Undirected Models:
Conditional Bayes Nets, Conditional Random Fields, Markov Random Fields.
 Selected Applications of Probabilistic Graphical Models.
It is *strongly* recommended to take this VO together with the
"Practical Excercises in Probabilistic Models" (UE, 1h) in the same semester.
There, the students will perform practical experiments with some of the methods
taught in the VO.
Teaching materials
Pdf versions of the Powerpoint slides used in the lecture will be made
available via KUSSS (weekly).

attended on a regular basis):
