【Abstract】 Rough set is a new data mining algorithm. In this paper,we propose a new attributes reduction algorithm based on the significance of attribute dependencies as heuristic information and add a certain variable precision. At last, a practical example is given to illustrate the proposed method and verifies its effectiveness.更多还原
