Why is the border between a virtual being and its world fuzzy
Brom, C. ; Lukavský, Jiří
In this article we first introduce the IVE project (Intelligent Virtual Environment - developed in 2005 at MFF UK, Prague) and ISMA model (Intention - Suitability - Materialisation - Advice) and describe related theoretical issues of the project. IVE is a simulator of large virtual worlds populated with virtual beings, which uses a new model called ISMA for virtual world representation. This model is inspired by Gibson's affordace theory and Bratman's theory of practical reasoning. Gradually we realized that some project results also have psychological and philosophical interpretation, which is being discussed in this article.

From the Brain in the Vat and Turing Test Towards Humanid Cognitive System
Wiedermann, Jiří
The modern theory of artificial cognitive systems sees these systems as autonomous embodied computational systems that situate themselves in the environment with the help of their sensomotoric units. Still, within the circles of computer theorists one can repeatedly hear an opinion that in principle cognition can be seen as a specific sort of computation and therefore one need not resort to embodiment in order to understand the nature of cognitive processes. We show that such a simplified view misses an essential part of cognitive systems – namely their active influencing the choice or even generation of their inputs.

Kurt Goedel - life, results and their significance
Běhounek, Libor
A survey (in Czech) of K. Gödel’s most important results and works in metamathematics, set theory, physics, and philosophy. A special attention is given to de-mything Gödel’s Incompleteness Theorems and to their consequences for computer science, artificial intelligence, philosophy, and other disciplines.

Mathematical Modelling of Generalization
Kůrková, Věra
Learning with generalization can be modeled using regularization, which was developed for a search of stable solutions of tasks for physics. In learning theory generalization can be understood as a certain kind of stability.
