If the attribute set Q=AD, A, D of information system S is condition attribute set and decision attribute set, such information system can also be called decision system (or decision table), V=Vq is the union set Vq of all attributes of q value domain, f is the information function specifying the attribute value of each object, namely: f: UQV. 2.2 Relative reduction of attribute For attribute set A, DQ , matrix unit element of relative discernibility matrix is:    	cache/cet-3934.pdf	txt/cet-3934.txt
