Generalization of Rough Sets Using Relationships Between Attribute Values
نویسنده
چکیده
The notion of rough sets is generalized by using an arbitrary binary relation on attribute values in information systems, instead of the trivial equality relation. The relation, not necessarily equivalence, between objects are defined in terms of relationships between attribute values. The adoption of other types of relations enables us to define various classes of rough set models. This study provides a basis for nonstandard rough sets. The results are complementary to that of investigations based on modal logic.

Parameterized rough set model using rough membership and Bayesian confirmation measures
A generalization of the original definition of rough sets and variable precision rough sets is introduced. This generalization is based on the concept of absolute and relative rough membership. Similarly to variable precision rough set model, the generalization called parameterized rough set model, is aimed at modeling data relationships expressed in terms of frequency distribution rather than ...
متن کاملThree Approaches to Missing Attribute Values: A Rough Set Perspective
A new approach to missing attribute values, based on the idea of an attribute-concept value, is studied in the paper. This approach, together with two other approaches to missing attribute values, based on "do not care" conditions and lost values are discussed using rough set methodology, including attribute-value pair blocks, characteristic sets, and characteristic relations. Characteristic se...

This paper introduces how to apply rough set classification and attribute reduction method in map generalization and provides solutions to several special cases arising in the map spatial data processing. Unlike the analysis in the past which focused solely on the attribute data of map, in this paper, rough set attribute decision table specific for the features of map data is created on the bas...
