| Abstract: | The attribute reduction of decision table based on the decision matrix is studied.With a counterexample we point out two errors in reference 3]: calculating the core of the decision table is not correct and the algorithm is not complete.Then,we present an improved decision matrix together with a method for attribute reduction of the decision table and an example shows that the improved method is effective and complete. |

| Keywords: | decision matrix discernibility matrix core attribute reduction complete algorithm |
