Abstract:There are some defects in the attribute set decomposition of decision table based on the attribute significance. The paper introduced a novel feature decomposition of decision table approach based on decision making. It analyzed the differences between the quality of approximation and the attribute significance to decision making. With the rough set theory, the relationships of condition attributes and decision attributes were considered increasing the attribute classification rate in the decision table, and a new attribute selection criterion was proposed. Then decision table was decomposed with the attribute selection criterion. ......
