RBF-networks with a dynamic architecture
Jakubík, Miroslav ; Mrázová, Iveta (advisor) ; Kukačka, Marek (referee)
In this master thesis I recapitulated several methods for data clustering. Two well known clustering algorithms, concretely K-means algorithm and Fuzzy C-means (FCM) algorithm, were described in the submitted work. I presented several methods, which could help estimate the optimal number of clusters. Further, I described Kohonen maps and two models of Kohonen's maps with dynamically changing structure, namely Kohonen map with growing grid and the model of growing neural gas. At last I described quite new model of radial basis function neural networks. I presented several learning algorithms for this model of neural networks, RAN, RANKEF, MRAN, EMRAN and GAP. In the end of this work I made some clustering experiments with real data. This data describes the international trade among states of the whole world.

Linear algebra algorithms visualization
Jakubík, Miroslav ; Pangrác, Ondřej (advisor) ; Hladík, Milan (referee)
This text focuses on problems of implementation of basic linear algebra algorithms. These algorithms are not too complicated, but there is a certain problem of using extremely huge or extremely small numbers which are not comprehensible to the human. Thus, in case of displaying intermediate outcomes, it is better when calculations are made human-like.
