 The written exam will takes place at 11.02.20 , 11h-13h, room HS 5

Topics

• Representation of uncertain information
• Bayesian networks
• Markov networks
• Evidence propagation in probabilistic networks
• Learning of probabilistic networks
• Revision of probabilistic networks
• Causal networks
• Decision Graphs
• Hidden Markov Models

Schedule and Rooms

Every student who wants to participate in the exercise must register her-/himself via the FIN Registration Service for the exercise. If you have any trouble with verifying the SSL certificate Jens Elkner could help you. While doing the registration, we kindly ask you to give an e-mail address of which incoming e-mail you check regularly.

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
• pass the exam

Exam: If you intend to finish the course with an exam, your are required to meet the certificate conditions. There will be a written exam after the curse. You can use your own not graphical and not programmable calculator.

Prerequisites

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

Slides

Note that the script may be subject to change (which will be stated in the news section above) during the course, i.e. page numbers may change.

Assignment Sheets

The assignment sheets will be published weekly at this location.

Due dates may be adjusted according to the lectures progress.
