the concept of indiscernibility matrix is proposed and the relation between discernibility matrix and indiscernibility matrix is shown. The advantage of indiscernibility matrix is pointed out. Then
an attribute reduction algorithm based on indiscernibility matrix is introduced. Compared with discernibility matrix algorithm
this algorithm greatly reduces running time and memory space.
