2A Ten-year Review of Granular ComputingJingTao Yao
Granular Computing
• Solving complex problems with granules.• Zadeh: a basis for computing with words.• Yao YY: a triangle: philosophical level thinking,
methodological level problem solving, computational information processing
• Bargiella and Pedrycz: human centered information processing: semantical data transformation, non-computational verification of information abstractions
3A Ten-year Review of Granular ComputingJingTao Yao
Basic Concepts
• Granules
• Granulation – Decomposition: coarser => finer – Construction: finer=> coarser
• Relationship
• Covering, partition
4A Ten-year Review of Granular ComputingJingTao Yao
Past, Present, and Future
• Standing on shoulders of giants• To know and to be known.• Find representative granular articles• Know what is going on• Understand trends• Databases
– ISI Web of Science
– IEEE Digital Library

Research Trends and Interaction
• Scientific growth is a diffusion process (Crane 1972: Invisible colleges)
• In the areas where researchers are aware of each other's existence, the curve of cumulative growth of publications and of authors entering the field follows a logistic pattern.– More new authors– Interacting with other domain– More publications

17A Ten-year Review of Granular ComputingJingTao Yao
Granular Computing Trend
• More linear like growth– Growth slowly– Less new authors (? did not check)
• Interaction– Fuzzy (6/15)– Rough (7/15)– Remaining (3/15)
• Hidden Fuzzy (2/3)• Hidden Rough (1/3)
– Others ? (interval computing, concept lattice, …) Runge-Kutta

Concluding Remarks
• Use standard term in Title, Abstract , and Keywords. (to be known)
– Granular Computing, GrC– Searchable from bibliographic databases
• GrC researc grows healthily but still have long way to go -> need more interaction
• Interact with other domain– GrC shares many thoughts with other domain especially in
philosophical level– Come (Invite people from other domains, WI-IAT-BIBM) – Go (Attend, submit GrC papers to other conferences, journals)
• New blood
