Model V1 s realistickou distribucí funkčních typů neuronů v rámci kortikálních vrstev
Moudřík, Josef ; Brom, Cyril (advisor) ; Sýkora, Ondřej (referee)
There have been identified two functionally different neuron classes in the primary visual cortex (V1), so-called simple and complex cells. These cells differ in reactions to various stimuli and their development has been successfully simulated in one computational model of V1. This model, however, simulates both classes in separate layers corresponding to layers 4C and 2/3 in V1. On the contrary, experiments have shown that both categories are - in different proportions - present in both layers. In this thesis, a computational model with a realistic distribution of complex and simple cells is presented. To increase its authenticity, I incorporate long-range excitatory and short-range inhibitory lateral cortical connections as found in animals, overcoming one drawback of previous models that used long-range inhibition. To assess my model, two measures of orientation selectivity - circular variance and orientation bandwidth - were computed for each simulated neuron. Using this measures, I compared my model with data from macaque monkey. In line with biological findings, my model develops a wide diversity of orientation selectivity. Moreover, it develops maps of orientation preference and realistic receptive fields.

Artificial intelligence for real-time strategic games
Sýkora, Ondřej
Title: Artificial intelligence for real-time strategic games Author: Ondřej Sýkora Department: Department of Theoretical Computer Science and Mathematical Logic Supervisor: Mgr. Cyril Brom Supervisor's e-mail address: brom@ksvi.mff.cuni.cz Abstract: Among the computer game players, real-time strategy games (RTS) are one of the most popular genres. Despite of this fact, there is a very low number of publicati- ons concerning this genre. In this thesis we study the problem of an action selection in the real-time strategy games using methods based on Markov decision processes. In the first chapters we introduce the genre of real-time strategy games from the game designer's perspective as well as from the view of an artificial intelligence researcher. We give an introduction to the Markov decision processes and to methods designed to solve them. We propose a solution of the problem of an action selection based on Markov decision problem solving using a discrete-event simulation of the real-time strategy game. We test the clarity of the proposed method and its properties. Keywords: real-time strategy game, Markov decision process, Expected Outcome, bandit- based planning, discrete-event-simulation 6

Comparison of Two British Referendums on European Union membership in 1975 and 2016
Sýkora, Ondřej ; Kasáková, Zuzana (advisor) ; Kłusek, Johana (referee)
This bachelor thesis deals with comparison of two referendums held in the United Kingdom of Great Britain and Northern Ireland in which British people decided about EEC/EU membership. These referendums were held in years 1975 and 2016. In 1975 people voted to stay in EEC, whereas in 2016 the exact opposite decision was made. The comparative method which is used in this thesis is applicated to analyse selected criteria. These are political background of the referendum, renegotiation of membership terms and the form and the results of the referendum itself. The comparative method is used to reach the goal of the thesis which is to reveal differences and similarities between the two referendums. Several differences explaining the opposite outcomes of the referendums were discovered as a result of the comparison.
