Reduction of the decision table: A rough approach
Authors:Shrabonti Ghosh  Ranjit Biswas  S S Alam
Abstract:In this article, we generalize Pawlak's rough approach for simplifying the decision table in an information system. We consider an information system where attribute values are not always quantitative, but are rather subjective, having vague or imprecise meanings. Some objects may have attribute values that are almost identical; that is, they cannot be distinguished clearly by the attributes. This observation is analyzed here being based on fuzzy proximity relations on different domain of attributes. Finally we find out the minimal solution of the table. © 2004 Wiley Periodicals, Inc.
