Using artificial intelligence to monitor the state of the machine
Kubisz, Jan ; Kroupa, Jiří (referee) ; Kovář, Jiří (advisor)
Diploma thesis focus on creation of neural network’s internal structure with goal of creation Artificial Neural Network capable of machine state monitoring and predicting its remaining usefull life. Main goal is creation of algorithm’s and library for design and learning of Artificial Neural Network, and deeper understanding of the problematics in the process, then by utilising existing libraries. Selected method was forward-propagation network with multi-layered perceptron architecture, and backpropagation learning. Achieved results was, that the network was able to determine parts state from vibration measurement and on its basis predict remaining usefull life.

Data Mining Case Study in Python
Stoika, Anastasiia ; Burgetová, Ivana (referee) ; Zendulka, Jaroslav (advisor)
This thesis focuses on basic concepts and techniques of the process known as knowledge discovery from data. The goal is to demonstrate available resources in Python, which enable to perform the steps of this process. The thesis addresses several methods and techniques focused on detection of unusual observations, based on clustering and classification. It discusses data mining task for data with the limited amount of inspection resources. This inspection activity should be used to detect unusual transactions of sales of some company that may indicate fraud attempts by some of its salespeople.

Improving Bots Playing Starcraft II Game in PySC2 Environment
Krušina, Jan ; Škoda, Petr (referee) ; Smrž, Pavel (advisor)
The aim of this thesis is to create an automated system for playing a real-time strategy game Starcraft II. Learning from replays via supervised learning and reinforcement learning techniques are used for improving bot's behavior. The proposed system should be capable of playing the whole game utilizing PySC2 framework for machine learning. Performance of the bot is evaluated against the built-in scripted AI in the game.

Application of Machine Learning Algorithms for the Generation of Checking Circuits
Lelkes, Olivér ; Krčma, Martin (referee) ; Kaštil, Jan (advisor)
Tato diplomová práce se zabývá využitím algoritmů strojového učení pro konstrukci hlídacích obvodů. Práce obsahuje popis principů hlídacích obvodů, jejich existující implementace a ostatní teoretické znalosti vztahující se k systémům odolným proti poruchám. Práce je zaměřena na aplikaci hlídacích obvodů na hardware komponentech se sekvenční logikou. Algoritmy strojového učení jsou trénovány pomocí datových množin, které se skládají ze vstup-výstup sekvencí hardwarových komponentů a ukládají se jako časové řady. Cílem práce je určení vhodnosti jednotlivých algoritmů pro jejich aplikaci v hlídacích obvodech. Pro dosažení tohoto cíle, bylo provedeno srovnání vybraných algoritmů strojového učení. Součástí práce je popis parametrů algoritmů a generování datových sad. Práce taktéž zahrnuje experimenty provedeny na dolnopropustném FIR filtru a jejich vyhodnocení. Podle výsledků experimentů je diskutováno, které algoritmy jsou použitelné v hlídacích obvodech.

Classification of heart beats using artificial neuronal networks
Doležalová, Radka ; Vítek, Martin (referee) ; Ronzhina, Marina (advisor)
This work deals with using of artificial neural networks (ANN) for ECG classification. The issue of ECG and ANN technique are described theoretically at first, the next section describes use of Matlab to design ANN and graphical user interface. ECG data (namely QRST segments from the orthogonal X- lead from seven phases of the experiment) obtained from experiments in isolated hearts of rabbits are used for learning and testing of the classifier. The result of this work is the software with GUI that allows user to set various parameters and structure of ANN. After learning phase, ANN realized in this work able to classify cardiac cycles according to their morphology into seven groups.

Application of Machine Learning Algorithms for Generation of Checking Circuits
Lelkes, Olivér ; Mičulka, Lukáš (referee) ; Kaštil, Jan (advisor)
This bachelor thesis deals with application of machine learning algorithms for generation of checking circuits. It contains detailed descriptions of the individual algorithms of machine learning which have been chosen to achieve this purpose. Except familiarization with it's theoretical properties there are also parts devoted to the specific utilization of the mentioned algorithms in the form of classifiers. Classifiers can work with different settings which influence the accuracy of the learning and the subsequent classification. The differences between the individual classifiers and their settings are illustrated in the experimental part of the thesis. Experiments were conducted on various circuits, including the control units of the robot, developed on the Department of Computer Systems, Faculty of Information Technology, Brno University of Technology.

Machine-Learning in Natural Language Processing
Otrusina, Lubomír ; Šilhavá, Jana (referee) ; Smrž, Pavel (advisor)
This beachelor's thesis deals with word sense disambiguation problem using the machine learning techniques. There are shortly presented problems of word sense disambiguation and its timeline. There are described methods and approaches, especially the naive Bayes classifier that is implemented in the system. There's illustrated a simple example of using this classifier. In a practical section is described project of system based on naive Bayes classifier including description of various algorithms used in the system. Finally there are described evaluation and analysis of the system. This created system took part in an international competition on semantic evaluation workshop SemEval-2007.
