Abstract

In term of researching attribute reduction based on tolerance rough set, this paper researches relation between definitions of reduct in set-valued decision system. The results help us deeply understand characteristic of reduct’s definition in set-valued decision system, also it is a theory foundation in order to create new and efficiency methods. For attribute reduction problems, the most important issue is to minimize the time complexity of attribute reduction algorithms. There have been many methods for attribute reduction, but finding reducts in these methods is almost performed on initial object set. In this paper, we propose a method for selection representative object set from initial object set to solve attribute reduction problem in set-valued decision system.
