Abstract :
Attribute reduction is one of the most important topics in rough set theory. Many types of attribute reduction have been defined in crisp decision tables. In this paper, the concept of distribution reduction in fuzzy decision tables is introduced. The judgments theorems and discernibility matrix with respect to distribution reduction are obtained, from which an approach to find all reducts in a fuzzy decision table is given.
