Matrix Description for Attribute Reduction Based on Skowron Discernibility Matrix

At present,there are no researcheres using matrix method to design attribute reduction algorithm based on Skowron discernibility matrix.Aiming at this problem,in this paper,a new matrix is proposed,and an attribute reduction based on the new matrix is provided.It is proved that the new attribute reduction definition is the same as that based on Skowron discernibility matrix.It uses the matrix of attribute to define the significance of attribute,and designs a new attribute reduction algorithm based on Skowron discernibility matrix.Example proves the validity of the algorithm.
