RST 2015  Warsaw, June 29


The ROUGH SET THEORY (RST) SERIES OF WORKSHOPS is devoted to the state-of-the-art and future prospects of ROUGH SETS considered from a theoretical standpoint. ROUGH SETS were introduced by Zdzisław Pawlak in the early eighties and developed further as a mathematical method of knowledge representation and processing under uncertain data and incomplete information. Nowadays, ROUGH SET THEORY is widely recognised to have a great importance in several fields, which is witnessed by the increasing number of papers concerned with applications and theoretical foundations of ROUGH SETS.

The sixth RST workshop will be held at the University of Warsaw, The Faculty of Mathematics, Informatics and Mechanics, Warsaw, Poland, June 29, 2015. The present edition of RST WORKSHOP comprises the special track:


Therefore potential authors may submit their contributions to the main (multi-topic) part of the workshop or to the special track.

Invited Speakers

Mihir Chakraborty, Foundations of Rough Sets

Pradipta Maji, Rough-Fuzzy Clustering and Its Applications

Mikhail Moshkov, Decision Rule Systems and Decision Trees over Finite Binary Information Systems (talk co-authored with Beata Zielosko)

Jan Rauch, GUHA Method and Association Rules


As in the previous editions of RST WORKSHOP the authors may submit full papers or extended abstracts. It is also expected that one of the authors will present their paper at the workshop.

The authors of abstracts are asked to send their submissions to the RST’2015 Chairs:

Marcin Wolski

Dominik Slezak

All accepted papers will be available here.
