Abstract:Through combining the discretization algorithm of continuous attributes with attribute reduction algorithm, this paper firstly did a discretization on continuous attributes columns, and got a new decisionmaking table. Then did attribute reduction on it, dealt with the problem of getting inaccurate reduction attributes on account of thinking about notcontinuous attributes during the process of attribute reduction. Finally an illustrated example shows that the way has preferable practicality and availability,can commendably apply to data mining project which contains plentiful continuous attributes. ......
