Detection of poorly differentiated cardiac arrhythmias
Kantor, Marek ; Ronzhina, Marina (referee) ; Novotná, Petra (advisor)
This thesis focusses on the detection methods of atrial fibrilation, atrial flutter and sinus rhythm from ECG. Thesis also concentrate on the description of this arrhythmias and the learning algorithms used. In this thesis are implemented several classification approaches. For extraction of features is used convolution neural network and classification artifitial neural network. Selected 1D CNN method achived classification accuracy global F1 - score is 91 %. Moreover, the proposed CNN optimized with GA appears to be fast shallow network with better accuracy than the deep network. Created model are used for classification other type of arrhythmias too.

ECG based atrial fibrillation detection
Plch, Vít ; Kolářová, Jana (referee) ; Ronzhina, Marina (advisor)
This diploma thesis deals with detection of atrial fibrillation from HRV, classification of Poincare map and in the end the divide into two groups, one with detected atrial fibrillation and one not. The result is the decision on which variables are statistically significant for the identification of atrial fibrillations and which are not, and classification of the ECG signals with Bayes and Lavenberg-Marquardt neural networks. Bayes neural network with 23 neurons in hidden layer is best with F1 measure = 83,6 %, Sensitivity = 88,1 % and Specificity 94,5 %.

Analysis of Use of Graduates from Faculty of Informatics and Statistics University of Economics in Prague
Řepík, Martin ; Molnár, Zdeněk (advisor) ; Voříšek, Jiří (referee)
This thesis deals with the analysis of informatics fields of study taught at public universities in the Czech Republic. The aim is to describe degree courses and their comparison with the teaching of informatics at the Faculty of Informatics and Statistics of the University of Economics in Prague. At the end the courses taught at FIS University of Economics in Prague are confronted with the statistics of graduates based on information from a database of personal agency Grafton Recruitment. Based on this are defined recommendations for further improvement of teaching of informatics at FIS University of Economics in Prague.
