Informační analýza dat ze sčítání lidu pomocí statistických modelů
Grim, Jiří ; Hora, J. ; Boček, Pavel ; Somol, Petr ; Pudil, P.
We describe a new method of information oriented data analysis (data mining) based on a quick evaluation of a virtual list of several hundreds of thousands of sub-populations. The sub-populations can be ordered according to different criteria like conditional probability of a value, conditional entropy of a variable or mutual informativity of a pair of variables. In this way we can identify causal relations between values and variables in a qualitatively new way.

Klasifikace obrazu - návrh klasifikátoru
Klimešová, Dana ; Ocelíková, E.
This paper presents overview of the mostly used classification approaches and shows the possibility of the approach based on the maximum entropy theory that can optimally describe the spatial data distribution and gives actual error estimation. The approach is highly recommended in case we are not able to test the assumptions of given method.

Modelově orientované řízení pro paralelní kinematiky robotů
Belda, Květoslav ; Böhm, Josef ; Valášek, M.
The paper deals with the application of the model-based control approach within robotic system that includes the parallel structure and adequate drives. As an example, several prototypes of planar parallel redundant structures driven by DC motors are used. The suitable form of mathematical model, both mechanical and drive part, will be introduced and subsequently used for control design. The design is based on discrete predictive control, which can compete and surpass the classical feedback strategies.

Factorizace 2-D polynom
Ježek, Jan ; Zezula, P.
Many algorithms are solving the problem of 1-D factorization. One of them was used and generalized to 2-D. This simple step brings new different difficulties up. Nevertheless, by no means could be the matter of 2-D factorization announced as completely investigated. Just a case with explicitly defined causality in both variables is offered in this paper. The numerical implementation of the algorithm below is the matter of ongoing labor.
