Reinforcement Learning for Robotic Soccer Playing
Brychta, Adam ; Švec, Tomáš (referee) ; Smrž, Pavel (advisor)
The aim of this thesis is to create a reinforcement learning agent that is able to play a soccer. I'm working with the deep Q-learning algorithm, which uses deep neural network. The practical part of this work is about implementing the agent for reinforcement learning. The goal of the agent is to choose the best action possible for a given situation. The agent is being trained in a variety of scenarios. The result of this thesis shows an approach to control soccer player using machine learning.

Recognizing People and Their Activities in Video from Security Cameras
Saloň, Juraj Samuel ; Švec, Tomáš (referee) ; Smrž, Pavel (advisor)
The aim of this thesis is to design and develop a system capable of recognizing the activities of people from surveillance cameras. Special attention is paid to the concept of complex situations or events that are defined by relations between identified objects. The first part surveys state-of-the-art techniques for object recognition, object tracking, and recognition of activities relevant to the realized solution. The second part describes the design and implementation of the devised system. It takes advantage of specific relations among two or more objects that are identified in video recordings, such as "person getting out of the car" or "one or more people met with a person of interest and they left together". Results are evaluated on video data extracted from available datasets and manually annotated. The mean average precision metric (MAP) on the data is reported.

Multiple-Context Trust Model for a Social Network Using Personality Analysis
Švec, Tomáš ; Zbořil, František (referee) ; Samek, Jan (advisor)
Tato diplomová práce navazuje na bakalářskou práci, ve které byl vytvořen model důvěry pro sociální síť Facebook. Do tohoto modelu jsou zapracovány připomínky z konference UMAP 2013 a ověřena jeho škálovatelnost a flexibilita. V další části práce jsou uvedeny základní termíny z psychologie osobnosti a zkoumána závislost důvěry na osobnosti uživatele. Je vybrán model Big Five k reprezentaci charakteru uživatele a navržen dotazník, u nějž bude zkoumána korelace s modelem důvěry. Tato korelace je na základě sociologických poznatků odhadnuta a později ověřena na reálných uživatelích sociální sítě Facebook.

Support for Sagrada Game on Mobile Phone with OS Android
Trněný, Jan ; Švec, Tomáš (referee) ; Smrž, Pavel (advisor)
The aim of this thesis is to create support application for board game Sagrada on mobile devices with OS Android. The solution consist of detection and recognition of the game pattern card and dices on board using the OpenCV library. Subsequently, support is provided, in any state of the game, for points calculation and rules checking for any number of players. These functions allow management of data for multiple users on one mobile device and help with faster rules checking and points calculation. Functions also help for beginners in understanding the game.

Evaluation of Trust or Reputation Based on Social Network Analysis
Švec, Tomáš ; Malačka, Ondřej (referee) ; Samek, Jan (advisor)
This thesis' goal is to apply the terms trust and reputation from the point of view of artificial intelligence to social network analysis methods. It evaluates current available interactions for a model of trust considering various social networks. A mathematical model of trust for Facebook is designed and described in further parts. This model had been implemented in Python programming language. Experiments regarding this thesis are conducted on a sample amount of Facebook users and furthermore analyzed from the perspective of both artificial intelligence and social psychology.

Vývojové trendy demokratických systémů v postkomunistických zemích
ŠVEC, Tomáš
The thesis deals with the development trends of democratic systems in post-communist countries, specifically in the Czech Republic and Poland. It examines how democratic systems were established in those countries and what the changeover to democracy was like. It describes the key events that led to the fall of communist regimes in those countries. The emphasis is put on opposition forces. Then it tries to describe the development trends of democratic systems in the 1990s, especially from the point of view of the party system and parliamentary elections. The thesis deals with political parties and political developments after individual parliamentary elections. The work also surveys the current political situation in the Czech Republic and Poland. The work tries to answer the question, how both states developed from a democratic point of view and the key point is also a comparison of both states.

Supporting Board Game Nemesis on Android Mobile Phone
Štěpánek, Miroslav ; Švec, Tomáš (referee) ; Smrž, Pavel (advisor)
The aim of this thesis is to create a mobile application for the board game Nemesis designed for the Android system, which will allow the user to find out information about the game components during the game. The solution consists of two main parts the first is a model created with the help of the Tensorflow library, which is responsible for the detection of these components. The second is the application itself, which receives results from the model and displays the resulting information to the user. This makes the game easier for the user and helps to speed it up. The resulting system can be modified so that the application can be used for other games.
