Motivation: The dream of creating artificial devices that reach or outperform human intelligence is an old one, but a computationally efficient theory of true intelligence has not been found yet, despite considerable efforts in the last 50 years. Nowadays most research is more modest, focussing on solving more narrow, specific problems, associated with only some aspects of intelligence, like playing chess or natural language translation, either as a goal in itself or as a bottom-up approach. The dual, top down approach, is to find a mathematical (not computational) definition of general intelligence. Note that the AI problem remains non-trivial even when ignoring computational aspects. Contents: In this course I develop such an elegant mathematical parameter-free theory of an optimal reinforcement learning agent embedded in an arbitrary unknown environment that possesses essentially all aspects of rational intelligence. Most of the course is devoted to giving an introduction to the key ingredients of this theory, which are important subjects in their own right: Occam's razor; Turing machines; Kolmogorov complexity; probability theory; Solomonoff induction; Bayesian sequence prediction; agents; sequential decision theory; adaptive control theory; reinforcement learning; Levin search and extensions.

After his PhD in theoretical particle physics in 1995, he developed algorithms in a medical software company for 5 years. Since 2000 he has published over 35 research papers, while working as a senior researcher at the Artificial Intelligence institute IDSIA in Lugano, Switzerland. His current interests are centered around reinforcement learning, algorithmic information theory and statistics, universal induction schemes, adaptive control theory, and related areas. In his recently published book "Universal Artificial Intelligence" (Springer, EATCS, 2004), he unifies sequential decision theory with algorithmic information theory. Since 2003, he has also been an honorary official lecturer at the Technical University Munich. Homework task is available from page http://www.cs.helsinki.fi/teemu.roos/uaicourse06/homework.html |
