Neural Networks Classifier Design using Genetic Algorithm
Tomášek, Michal ; Vašíček, Zdeněk (referee) ; Mrázek, Vojtěch (advisor)
The aim of this work is the genetic design of neural networks, which are able to classify within various classification tasks. In order to create these neural networks, algorithm called NeuroEvolution of Augmenting Topologies (also known as NEAT) is used. Also the idea of preprocessing, which is included in implemented result, is proposed. The goal of preprocessing is to reduce the computational requirements for processing of benchmark datasets for classification accuracy. The result of this work is a set of experiments conducted over a data set for cancer cells detection and a database of handwritten digits MNIST. Classifiers generated for the cancer cells exhibits over 99 % accuracy and in experiment MNIST reduces computational requirements more than 10 % with bringing negligible error of size 0.17 %.

Intelligent Music Player for Android
Tomášek, Michal ; Rozman, Jaroslav (referee) ; Kalmár, Róbert (advisor)
Today's market is full of different kinds of music players. However there is no music player using prediction, which would be able to work with usual usage and in real time. This bachelor's thesis deals with the design and implementation of a music player with implemented prediction. The creation of high quality architecture for this application and the choice of appropriate prediction algorithm are emphasized. At first, the category of methods of machine learning and afterwards the algorithm are determined. The final prediction algorithm is divided into a several sections, therefore it is necessary to pick or create a solution for all its parts. The outcome of this project is the music player for Android OS which would be able to predict and learn from a user interaction in real time.

Analysis of pressure distribution in the variant detector with three aperture by CAE system
Tomášek, Martin ; Vyroubal, Petr (referee) ; Maxa, Jiří (advisor)
This master`s thesis analyzes the pressure distribution on the premises of scintillation detector secondary electron in the variant with three aperture. The aim of this study is analyzing the fluid flow depending on the application of the third aperture in the entrance of the detector, thus creating more self-pumped chamber, which is responsible for ensuring a better distribution of pressure in the premises of the detector. The result of the analysis would be determining how to change parameters within the detector. If it is found that application of the third aperture has a positive effect on water flow in the premises of the detector, this arrangement may be used for improvement of the detector. Master`s thesis is divided into several chapters. First describes the basic principles of electron microscopy, including sample preparation, conditions for the proper functioning of microscopes and sharing different types of electron microscopes. The next chapters describe briefly the physical descriptions of gases flow in low pressures and small apertures, the mathematical models and simulation software used in this analysis. The analysis is done in SolidWorks with the module called Cosmos FloSimulation. The conclusion summarizes the results of the analysis, including graphical representations of simulation.
