The 2021 International Conference on Cognitive analytics, Granular computing, and Three-way decisions (CCGT`21) will be held on October 15-19, Shanghai, China. The conference will be co-located with International Conference on Belief Functions October 15-19, 2021 in Shanghai, China. This will be first conference with the aim of presenting and sharing the innovative results in the areas of three-way decisions, granular computing, cognitive analytics and the research fields that are emerging as a result on research focusing on the relationship between the three fields. The conference will provide a great opportunity for academia and industry linkages and research collaborations both in terms of new theoretical solutions and applications.

The conference will be held as a hybrid of face-to-face and virtual online meetings. More details will be announced later.
