This year marks a monumental milestone for our society and the global scientific community. We invite you to join us in honoring the legacy of Professor Zdzisław Pawlak (10 Nov 1926 – 7 Apr 2006) on the 100th anniversary of his birth.

Rough Sets were introduced by Zdzisław Pawlak in the early ’80s and developed further as a method of knowledge representation and processing based on uncertain data and incomplete information. Nowadays, Rough Set theory is widely recognized to have great importance in several fields, including artificial intelligence, mathematics, knowledge representation and machine learning, as evidenced by the increasing number of works concerned with its applications and theoretical foundations.

The Report: 1. Anniversary Panel Session: Rough Sets Turn 40: Uncertainty Management Perspective 2. Keynote Talk by Andrzej Skowron: Perceptual Rough Set Approach in Interactive Granular Computing
