Aplikace metody spojitého Q-učení
Věchet, S. ; Krejsa, Jiří ; Míček, P.
Standard algorithm of Q-Learning is limited by discrete states and actions and Q-functionis usually represented as discrete table. To avoid this obstacle and extendthe use of Q-learning for continuous states and actions the algorithm must bemodified and such modification is presented in the paper. Straightforward way isto replace discrete table with suitable approximator.

Použití LWR kompenzátoru pro řízení aktivního magnetického ložiska
Březina, Tomáš ; Pulchart, J. ; Krejsa, Jiří
The active magnetic bearing (AMB) control is a complex problem, as it is fast, unstable and nonlinear system. The contribution deals with the simulation verification of AMB control using conventional PSD controller with nonlinear forward compensator. The automated universal approximator based on locally weighted learning (namely Receptive Field Weighted Regression - RFWR method) is used as the compensator.

Aproximace modelu stability kráčivého robotu
Krejsa, Jiří ; Grepl, Robert ; Věchet, S.
The paper compares global and local approximation methods used for walking robot stability model. Global approximators are represented by feedforward multilayer neural network (FFNN) trained by gradient method; local approximators are represented by Locally Weighted Regression (LWR) and Receptive Field Weighted Regression (RFWR) methods.

Implementation of information system Unicorn Universe at Unicorn College
Krejsa, Jiří ; Švecová, Lenka (advisor) ; Havelka, Martin (referee)
The essential theme of this bachelor theses is the problems in implementation of information system into organization. The main aim of this work is to describe selected processes, that are used for IS implementation and to decompose the application of these procedures on one particular example. This theses should demonstrate the variability of used methods and simultaneously prove the complexity of exercise where the theoretical procedure is being used in concrete situation. Chosen methods are described on the basis of available literature and electronic resources from domestic and foreign authors. Practical part makes accessible methodics that are used by one concrete company, which attend in the long term to information system implementation. This part also assays one of the projects, where this company applied its' methodics. The main contribution of my theses is transparent description of system implementation on concrete example. Intercepted results confirm the severity of exercise, which is being repetitively solved nowadays by medium and big organizations. At the same time these results justify attention which is being given to the implementation of information system.
