Lecture - The Logic of Knowledge Bases SS 2018

Submitted by Jens Claßen on 15. February 2018 - 16:37

This course is about the logic of knowledge bases, in two distinct but related senses. On the one hand, a knowledge base is a collection of sentences in a representation language that entails a certain picture of the world represented. On the other hand, having a knowledge base entails being in a certain state of knowledge where a number of other epistemic properties hold. One of the principal aims of this course is to develop a detailed account of the relationship between symbolic representations of knowledge and abstract states of knowledge. Students wishing to attend the course should be familiar with first-order predicate logic.

Proseminar Artificial Intelligence SS 2018

Submitted by stf on 15. January 2018 - 12:02

The proseminar will be on different (sub-)topics from artificial intelligence. We largely follow the lines of the well known textbook by Stuart Russell and Peter Norvig "Artificial Intelligence - A Modern Approach".

We implement a peer review process for this seminar. That is, every student will read some other students' term paper and provide feedback in form of a written review. This shall not only deepen your understanding of the other topics, but it also introduces you to the academic review process.

An L²P-Lernraum of the course contains more info and material (for participants only!).

Seminar "Reasoning, Planning, and Scheduling with Uncertainty"

Submitted by Till Hofmann on 13. January 2018 - 13:46

In this seminar, we will study uncertainty in the context of reasoning, planning, and scheduling. For reasoning about actions, we will look into stochastic extensions of the Situation Calculus, a well-known formalism for reasoning about dynamic domains. In the classical Situation Calculus, all actions are deterministic. In this seminar, we will learn about extensions that allow non-deterministic and probabilistic actions. For planning, we will investigate probabilistic extensions to classical planning frameworks such as the Planning Domain Definition Language (PDDL) and compare them to Markov Decision Processes (MDPs). For scheduling, we will learn about mechanisms for solving scheduling problems with probabilistic task durations.

Seminar "Selected Topics on Planning and Plan Execution for Robotic Systems" SS 2017

Submitted by Till Hofmann on 9. January 2017 - 18:41

In this seminar we will study plan generation and plan execution in robotic domains. While planning deals with the problem of finding suitable actions to accomplish a certain goal, plan execution and monitoring on robots come with additional problems: The agent's knowledge is no longer complete, the environment may change during plan execution, humans and other agents may interfere with the agent's actions, and resource and temporal constraints need to be honored. The plan executive needs to execute actions physically on a robot, adapt to changes during execution, and repair the current plan or replan if necessary. In this seminar, we will look at various methods to deal with those problems and we will investigate how these methods are applied on real-world robotic systems.

Seminar Forgetting and Relevance SS 2016

Submitted by Christoph Schwering on 30. December 2015 - 20:59

In this seminar we will study concepts of forgetting and relevance developed in the field of Knowledge Representation. Humans not only forget unintentionally but also intentionally, for example, when they obtain new information and delete previous contradicting and apparently false information. In fact, humans usually do not forget irrevocably; we can bring back memories and reconstruct forgotten knowledge. In formal languages as studied in KR, however, even supposedly simple forgetting often turns out very difficult. In this seminar, we will study techniques for forgetting in KR languages such as predicate logic, description logics, or answer set programs. Related to forgetting is the concept of relevance among different facts. For example, when some fact is to be forgotten, this may also affect other facts relevant to the forgotten fact. Relevance is useful to develop tractable reasoning and handling inconsistencies in a knowledge base.
