Lecture Bayesian Networks

Winter Term 2009/2010



No consultation on 28.01.2010 due to lack of inquiries. If you have questions, just drop by my office.

If you need a Schein, please sent my your details (student ID, year of enrollment, course).

General Information

This page contains information about the lecture "Bayesian Networks" (Bayessche Netze) that is held in winter term 2009/2010 by Prof. Dr. Rudolf Kruse. This page is updated during the course.


  • Modeling of uncertainty and vagueness in expert systems
  • Representation of uncertain information in probabilistic networks (Bayesian networks / Markov networks)
  • Evidence propagation in such networks
  • Quantitative and structural induction of probabilistic networks from data
  • Other uncertainty calculi (Dempster-Shafer)
  • Applications

Conditions for Certificates (Scheine) and Exams

Certificate (Übungsschein): There are assignment sheets published every week. Assignments the solutions of which you want to present in the next exercise lecture have to be ticked beforehand on a votation sheet that is handed our prior to every exercise lecture. If ticked, you may be asked to present your solution in front of class. The solutions need not necessarily be completely correct, however, it should become obvious that you treated the assignment thoroughly. You are granted the certificate (Schein), if (and only if) you

  • ticked at least two thirds of the assignments,
  • presented at least two times a solution during the exercise, and
  • passed a small colloquium (approx. 10 min) or a written test (if there are more than 20 students) after the course.

Exam: If you intend to finish the course with an exam, your are not required to meet the certificate conditions. However, you are of course encouraged to also solve the assignments. Regarding the exam, please contact and negotiate a date and time with Prof. Kruse. The exam has to be announced to the Prüfungsamt two weeks prior to the exam date via this application form. The exam consists of a 20 to 25 minutes oral examination about the subjects presented during the course. Emphasis is put on understanding rather than formal details. The final marks will be in the following range: 1.0, 1.3, 1.7, ..., 3.7, 4.0, 5.0. If more than 20 students intend to do an exam, the oral exam may be converted into a written examination.

You should have background knowledge on fundamentals of computer science such as algorithms, data structures etc. Also, insights into probability theory are highly recommended.
