Approach for absolute attribute reductions in rough sets

Attribute reductions is one of the basic contents in rough sets and one of the most problem in knowledge acquisition. At present, the methods used are often Pawlakpsilas data analysis and Skowronpsilas discernible matrix methods. In this paper an approach for the set of all absolute attribute reductions is proposed based on the discernible attribute set. Finally, we also show the experimental results by examples.
