Laboratory of intelligent data analysis (LIDA)

The laboratory is devoted to a development and application of various methods for searching, assembly, analysis and interpretation of data and knowledge, particularly

• an optimisation of dynamic or repeating disposable data using graph theoretical structures    and real process modelling,
• a research and an application of methods for processing of multidimensional data with stochastic character,
• an application of the conceptual analysis in the areas of information searching, knowledge mining, natural language processing, knowledge management, …,
• an application of neural networks and other methods of machine learning in a comparative analysis,
• regular assembly of time-dependent data from Web pages and Web services, information extraction from semi-structured and/or non-structured sources, integration and deduplication of data.

Researchers:

• Dr. Ľubomír Antoni, PhD.
• Dr. Erik Bruoth, PhD.
• Prof. Dr. Katarína Cechlárová, DrSc.
• Dr. Peter Gurský, PhD.
• Dr. Ondrej Krídlo, PhD.
• Dr. Katarína Lučivjanská, PhD.

Lab administrator: Dr. Juraj Šebej, PhD.

Research infrastructure

The laboratory is situated at the seminary room LIDA that is equipped with projectors and interactive board and its variable arrangement supports team work, and allows organization of seminars and workshops. The laboratory exploits computational sources available in the Computing and network node.
