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.

On Spring of 2026 we invite you to the 12th International Joint Conference on Rough Sets (IJCRS 2026), which will take place in Cádiz (Spain) from May 26 to May 29, 2026. IJCRS is the principal international conference sponsored by the International Rough Set Society (IRSS).

The aim of the IJCRS conference is to be the main location for disseminating novel foundational results and practical applications, enabling the discussion of problems and exchange of ideas, as well as bringing together academic and industrial perspectives, centred around rough sets and related disciplines (such as granular computing, three-way decisions and fuzzy sets).

In may 2026 we welcome you to IJCRS 2026 and we invite you to enjoy the historic city of Cádiz!
