Reduction of Computation Cost in libSVM Using String Kernel Functions
 Kubernát, Tomáš ; Sehnalová, Pavla (referee) ; Michlovský, Zbyněk (advisor)
The goal of this thesis was to implement four string functions into the library libSVM . Then apply series of tests with variable parameters values affecting the individual string functions using the library and string functions. Using the results of experiments the speed and success of clasification of my implementation of string functions in library libSVM was compared with the implementation of string functions in program kernels . In this thesis there are also described procedures of all tests along with measured data and their graphical representation.

Increasing Classification Accuracy in libSVM Using String Kernel Functions
 Homoliak, Ivan ; Drozd, Michal (referee) ; Michlovský, Zbyněk (advisor)
Publication aims to explore dependencies of text classification used with string kernel functions. String kernel functions are here used to retrieve rate of similarity between two text strings. There are described experiments with single string kernel function and also experiments with combinations of them with arithmetic operations of adition and multiplication. Gathered results are aplied to detect spam messages of e-mail communication.
