| Abstract: | First, a method to form the generalized information table of a decision table is given.Then, according to the features of the generalized information table, an approach how to weigh the significance of condition attributes is acquired. At last, an algorithm is proposed to get the minimal attribute reduction of consistent and inconsistent decision table respectively. |
