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.
