Information system which solves scheduling
Procházková, Petra ; Brixí, Radim (advisor) ; Chlapek, Dušan (referee)
In first part of my thesis I deal with surveying of existing systems for preparing school timetables at secondary schools in Czech Republic and then I characterize them. This part also contains evaluation of satisfaction with these systems by their users. In second, practical part of my thesis I think up my own alternative algorithm for preparing timetables, which tries to eliminate problems, which users see in current systems.

Selected methods of artificial intelligence - artificial life and computer viruses
Hapala, Michael ; Jirků, Petr (advisor) ; Berka, Petr (referee)
The aim of this bachelor's thesis is to introduce a reader into the area of artificial intelligence, artificial life and computer viruses. The thesis is divided into chapters. First chapter deals with artificial intelligence, it tries to define natural intelligence and then also artificial intelligence. Next part of the thesis describes history of artificial intelligence from its beginings till current times, particular points are separated by years, in which they happenned. Second chapter deals with artificial life, it defines life and characterizes artificial life. Then it deals with cellular automata. It describes, what a cellular automaton is. It deals with von Neumann's kinematic model and celullar automaton and then characterizes particular cellular automata -- the Game of Life, Langton Qloops and Wolfram's one-dimensional cellular automaton. It describes the meaning of cellular automata, then Lindenmayer systems and other methods of artificial life -- artificial life and chaos and life simulators. Third chapter deals with computer viruses, their definition and beginnings. Then it describes classification of malware and techniques of computer viruses. Remaining part sorts viruses by target they infect, by their concealment strategy, by their location in memory and it mentions other types of viruses.

Využití imsetů při učení bayesovských sítí
Vomlel, Jiří ; Studený, Milan
This paper describes a modification of the greedy equivalence search (GES) algorithm. The presented modification is based on the algebraic approach to learning. The states of the search space are standard imsets. Each standard imset represents an equivalence class of Bayesian networks. For a given quality criterion the database is represented by the respective data imset. This allows a very simple update of a given quality criterion since the moves between states are represented by differential imsets. We exploit a direct characterization of lower and upper inclusion neighborhood, which allows an efficient search for the best structure in the inclusion neighborhood. The algorithm was implemented in R and is freely available.

Noisy-or classifier
Vomlel, Jiří
We discuss application of the noisy-or model to classification with large number of attributes. An example of such a task is categorization of text documents, where attributes are single words from the documents.

Hmotnostní a energetické toky v souvislostech podnikového environmentálního účetnictví
Farský, M. ; Neruda, M. ; Neruda, Roman
During the implementation of an environmental accounting system in a company, one of the most important pieces of information to obtain is a detailed understanding about material flows (raw materials, semi-finished products, final products and wastes) and flows of different types of energy inputs (buying, selling and wastage) when thinking about the consequences on the company. The authors, in the article: 1) study the question of the quantification of the flows, and the accuracy of their measurement, 2) provide an environmental accounting statement, with help of standards and indices, statistical trends analysis.
