| Abstract: | Attributes reduction is one of the important topics in rough set theory. For this reason, a concept of the closest approximate setis introduced and a new reduction method in decision table -the closest approximate reduction is studied. Example analysis shows the method is simple and effictive. |

| Keywords: | rough set decision table attributes reduction closest approximate reduction |
