In this paper, the relational structure is confined to the simplest kind, namely, binary relations. From different consideration, in granular computing, such a binary relational structure has been called a crisp/fuzzy binary granulation, or binary neighborhood system (FBNS). Intuitively, the set has been granulated into binary neighborhoods (generalized equivalence classes). Combining the two views, the simplest kind of \"real world\" model is BNS-space. From this view, the classical relational theory is the knowledge representation of the universe whose structure is a finite set of equivalence relations; in a \"real world\" relational theory, a finite set of crisp/fuzzy binary relations. Here knowledge representation is assigning meaningful names to binary neighborhoods (or equivalence classes in relational theory). Depending on the structures, the model can be useful in fuzzy logic or data mining. The focus of this paper is on data mining using granular computing. Experiments show that the computing is extremely fast and the cost of computing extra semantics is very small.","PeriodicalId":227374,"journal":{"name":"Proceedings Joint 9th IFSA World Congress and 20th NAFIPS International Conference (Cat.

It is true that the number of cases stored in the case library of a CBR system is directly related to the retrieval efficiency. Although more cases in the library can improve the coverage of the problem space, the system performance will be downgraded if the size of the library grows to an unacceptable level. The paper addresses the problem of case base maintenance by developing a method to reduce the size of large case libraries so as to improve the efficiency while maintaining the accuracy of the CBR system. To achieve this, we adopt the local feature weights approach. This approach consists of three phases. The first phase involves partitioning the case-base into different clusters. The second phase involves learning the optimal local feature weights for each case and the final phase involves reducing the case-base based on the optimal local weights. The paper focuses on the last two phases. To justify the usefulness of the method, we perform an experiment which uses efficiency, competence, and ability to solve new problems as the benchmark to verify our design.","PeriodicalId":227374,"journal":{"name":"Proceedings Joint 9th IFSA World Congress and 20th NAFIPS International Conference (Cat.
