6. Three-way granular computing, rough sets, and formal concept analysis.

*GRANULAR computing, *ROUGH sets, *INFORMATION processing, *CONCEPTS, *HEXAGONS
Abstract

Three-way granular computing is a paradigm of thinking and information processing in three granules. We introduce a framework of three-way granular computing based on a hexagon induced by a trisection of a set. This enables us to unify rough-set concept analysis and formal concept analysis. For an object granule (i.e., a subset of a universal set of objects), we construct three attribute granules. Conversely, for an attribute granule (i.e., a subset of a universal set of attributes), we construct three object granules. Rough-set concept analysis uses one kind of trisections to study four types of disjunctive formal concepts and the associated concept lattices. Formal concept analysis uses another kind of trisections to study four types of conjunctive formal concepts and the associated concept lattices. The eight concept lattices can be grouped into two classes such that four lattices in each class are isomorphic. [ABSTRACT FROM AUTHOR]

7. Structured approximations as a basis for three-way decisions in rough set theory.

Abstract

Abstract A major application of rough set theory is concept analysis for deciding if an object is an instance of a concept based on its description. Objects with the same description form an equivalence class and the family of equivalence classes is used to define rough set approximations. When deriving the decision rules from approximations, the description of an equivalence class is the left-hand-side of a decision rule. Therefore, it is useful to retain structural information of approximations, that is, the composition of an approximation in terms of equivalence classes. However, existing studies do not explicitly consider the structural information. To address this issue, we introduce structured rough set approximations in both complete and incomplete information tables, which serve as a basis for three-way decisions with rough sets. In a complete table, we define a family of conjunctively definable concepts. The structured three-way approximations are three structured positive, boundary and negative regions given by three sets of conjunctively definable concepts. By adopting a possible-world semantics, we introduce the notion of conjunctively definable interval concepts in an incomplete table, which is used to construct the structured three-way approximations. The internal structure of structured approximations contributes to sound semantics of rough set approximations and is directly and explicitly related to three-way decision rules.

8. Class-specific attribute reducts in rough set theory.

Abstract

The concept of attribute reducts plays a fundamental role in rough set analysis. There are at least two possibilities to define an attribute reduct. A classification-based or global attribute reduct is a minimal subset of condition attributes that preserves the positive region of the decision classification, namely, the positive regions of all decision classes, in a decision table. A class-specific, class-dependent, or local attribute reduct is a minimal subset of condition attributes that preserves the positive region of a particular decision class. While a classification-based reduct may not work equally well for every decision class, a class-specific attribute reduct is optimally tailored to a particular decision class. However, studies in rough set theory are dominated by classification-based reducts; there is very limited investigation on class-specific reducts. An objective of this paper is to draw attention to class-specific reducts. We systematically compare the two types of reducts and investigate their relationships with respect to both individual reducts and families of all reducts. It is possible to derive a class-specific reduct from a classification-based reduct and to derive a classification-based reduct from a family of class-specific reducts. The families of all class-specific reducts provide a pair of lower and upper bounds of the family of all classification-based reducts. Based on a three-way classification of attributes into the pair-wise disjoint sets of core, marginal, and nonuseful attributes, we examine relationships between the corresponding classes of classification-based and class-specific attributes. The union of the sets of class-specific core attributes is the set of classification-based core attributes. It is only possible to obtain an upper bound for the set of classification-based marginal attributes and a lower bound for the set of classification-based nonuseful attributes from the family of the class-specific corresponding sets of attributes.

9. Rough-set concept analysis: Interpreting RS-definable concepts based on ideas from formal concept analysis.

Author

Subjects
*PHILOSOPHICAL analysis, *BOOLEAN algebra, *ROUGH sets, *LATTICE theory, *PROPOSITIONAL calculus
Abstract

Based on ideas from formal concept analysis, this paper interprets the notions of RS-definable concepts (i.e., rough-set definable concepts) and the Boolean algebra of RS-definable concepts. We explicitly represent a RS-definable concept as a pair of an extension and an intension, where the extension is a set of objects and the intension is a family of sets of attribute-value pairs called avp-sets. An object in the extension satisfies at least one avp-set in the intension and each avp-set in the intension is satisfied by only objects in the extension. The two-directional connections produce an atomic Boolean algebra of RS-definable concepts, corresponding to the lattice of formal concepts in formal concept analysis. The Boolean algebra of RS-definable concepts is used to define and interpret a subset of objects through a pair of lower and upper approximations. The new formulation emphasizes on an in-depth conceptual understanding of rough-set concept analysis. [ABSTRACT FROM AUTHOR]

10. Covering based rough set approximations

Abstract

Abstract: We propose a framework for the study of covering based rough set approximations. Three equivalent formulations of the classical rough sets are examined by using equivalence relations, partitions, and σ-algebras, respectively. They suggest the element based, the granule based and the subsystem based definitions of approximation operators. Covering based rough sets are systematically investigated by generalizing these formulations and definitions. A covering of universe of objects is used to generate different neighborhood operators, neighborhood systems, coverings, and subsystems of the power set of the universe. They are in turn used to define different types of generalized approximation operators. Within the proposed framework, we review and discuss covering based approximation operators according to the element, granule, and subsystem based definitions. [Copyright &y& Elsevier]

17. On modeling similarity and three-way decision under incomplete information in rough set theory.

Abstract

Although incomplete information is a well studied topic in rough set theory, there still does not exist a general agreement on the semantics of various types of incomplete information. This has led to some confusions and many definitions of similarity or tolerance relations on a set of objects, without a sound of semantical justification. The main objective of this paper is to address semantics issues related to incomplete information. We present a four-step model of Pawlak rough set analysis, in order to gain insights on how an indiscernibility relation (i.e., an equivalence relation) is defined and used under complete information. The results enable us to propose a conceptual framework for studying the similarity of objects under incomplete information. The framework is based on a classification of four types of incomplete information (i.e., "do-not-care value", "partially-known value", "class-specific value", and "non-applicable value") and two groups of methods (i.e., relation-based and granule-based methods) for modeling similarity. We examine existing studies on similarity and their relationships. In spite of their semantics differences, all four types of incomplete information can be uniformly represented in a set-valued table. We are therefore able to have a common conceptual possible-world semantics. Finally, to demonstrate the value of the proposed framework, we examine three-way decisions under incomplete information.

Abstract

Attribute reduction plays an important role in the areas of rough sets and granular computing. Many kinds of attribute reducts have been defined in previous studies. However, most of them concentrate on data only, which result in the difficulties of choosing appropriate attribute reducts for specific applications. It would be ideal if we could combine properties of data and user preference in the definition of attribute reduct. In this paper, based on reviewing existing definitions of attribute reducts, we propose a generalized attribute reduct which not only considers the data but also user preference. The generalized attribute reduct is the minimal subset which satisfies a specific condition defined by users. The condition is represented by a group of measures and a group of thresholds, which are relevant to user requirements or real applications. For the same data, different users can define different reducts and obtain their interested results according to their applications. Most current attribute reducts can be derived from the generalized reduct. Several reduction approaches are also summarized to help users to design their appropriate reducts. [ABSTRACT FROM AUTHOR]
