| Abstract: | Based on researching interval attribute valued decision systems in rough set theory,a new approach attribute reduction in interval attribute valued decision systems is presented.First,analyzing technique is used to transform interval attribute valued decision table into the three-component decision table,and then the attribute reduction is induced using rough set theory.The experiment shows the method is effective. |
