Intelligent data analysis research

The research team is mainly involved in applied data analysis research, prepares describing, exploring,

predictive and prescriptive statistical analyses in fundamental and applied research tasks. In addition to data mining methods, in their data analyses they use bioinspired methods (genetic algorithms, fuzzy systems, neural networks - including in-depth analyses and self-organizing maps) combined with classical mathematical statistical methods.

Some previous tasks: handwriting recognition, creation of an international handwriting database, expert analysis of ecological databases, examination of the effectiveness of context and semantic analysis in automatic text classification tasks, improvement of optical quality control with MI methods, development of cow rumen probe data analysis algorithms.

Keywords: intelligent data analysis, data mining, statistics, genetic algorithms, fuzzy systems, neural networks, SOM
