A Methord For Information Granulation Based On Date Clustering

Granular computing is a kind of method for soluting uncertain problems based on structured thought. The tow basic tasks of granule computing are constructing the in-formation granular and soluting the problems by means of information granular.Based on the clustering analysis and hierarchical hyperbox model,this article constructing 1-neighborhood system, through this construction,it establishes a kind of nested information granulating method, which is corresponding with hierarchical hyperbox nested structure. Meanwhile, it presents a relative arithmetic.Furtherly, it combines with rough set model in the information system,and then it raised a new concept of attribute reduction which correspond with the nested structure of information granular.
