Doc. Ing. Petr Hájek, Ph.D., currently works as Associate Professor at the Institute of System Engineering and Informatics of the Faculty of Economics and Administration of the University of Pardubice. In 2006 he defended his dissertation thesis on the modelling of creditworthiness of municipalities using computational intelligence methods and in 2012 a habilitation thesis on the topic of credit rating modelling using soft computing methods. Doc. Hájek was a researcher of four projects of the Grant Agency of the Czech Republic focusing on the application of computational intelligence methods to support business decision-making. He was also a member of the research team of three other GA CR projects, one TA CR project and three projects commissioned by ministries.

Scientific interest:

  • Fuzzy systems, neuro-fuzzy systems and evolutionary fuzzy systems
  • Financial risk prediction using computational intelligence methods
  • Deep learning neural networks for spam prediction
  • Decision support systems under uncertainty

Scientific activities:

Doc. Hájek deals with methods of artificial and computational intelligence, especially fuzzy systems, neural networks, machine learning and systems integrating fuzzy systems, neural networks and evolutionary algorithms. He designed and applied a number of prediction models, including financial fraud prediction systems, economic performance prediction systems, social network and business platform spam prediction systems, and decision support systems in high-level uncertainty environments.

Prominent international cooperation:

  • dr. Wojciech Froelich – University of Silesia in Katowice, Poland
  • prof. Leonardo Vanneschi – Universidade de Lisboa, Portugal
