Time series prediction
Boková, Kateřina ; Pilát, Martin (advisor) ; Koubková, Alena (referee)
In this present work, we provide an overview of methods for time series modelling and prediction. We describe methods based on decomposition as well as methods based on the Box-Jenkins methodology. Moreover, we also discuss methods based on the ideas from computational intelligence -mainly neural networks. Thedescription of the methods is focused on the algorithmic aspects -we derive the ways in which the parameters of the models are set. The work also contains a software, which allows the user to apply the described methods to given time series and compare them among each other.

Computational Intelligence for Financial Market Prediction
Řeha, Filip ; Pilát, Martin (advisor) ; Mráz, František (referee)
Financial markets are characterized by uncertainty, which is associated with the future progress of world economics and corporations. The ability of an individual to forecast future market behaviour at least to a certain extent would give him an important competitive advantage on the market. The aim of this work is to explore neural networks and genetic programming as possible tools which could be used for financial markets forecasting and apply them on historical financial data. Experiments using neural networks and genetic programming were performed and the results show, that both tools can be employed successfully. On average, neural networks outperformed genetic programming in our experiments. In order to evaluate and visualize the results of our created strategies, the MarketForecaster application was implemented. Powered by TCPDF (www.tcpdf.org)

Meta-Parameters of Kernel Methods and Their Optimization
Vidnerová, Petra ; Neruda, Roman
In this work we deal with the problem of metalearning for kernel based methods. Among the kernel methods we focus on the support vector machine (SVM), that have become a method of choice in a wide range of practical applications, and on the regularization network (RN) with a sound background in approximation theory. We discuss the role of kernel function in learning, and we explain several search methods for kernel function optimization, including grid search, genetic search and simulated annealing. The proposed methodology is demonstrated on experiments using benchmark data sets.
