The Rough Bayesian Model for Distributed Decision Systems

  • Dominik Ślȩzak
Part of the Lecture Notes in Computer Science book series (LNCS, volume 3066)


The article presents a new approach to understanding the concepts of the theory of rough sets basing on the inversive probabilities derivable from distributed decision systems. The Rough Bayesian model – a novel probabilistic extension of rough sets related to Bayes’ factor and Bayesian methods of the statistical hypothesis testing is proposed. Advantages of the Rough Bayesian model are illustrated by the examples.
