摘要
提出一种基于新型协调量化容差关系的不完备数据补齐算法。首先求出属性值不完备对象的容差类,结合属性的重要度,将容差类里面的对象容差关系量化,再根据决策规则独立原则,在尽可能保持系统协调性的前提下对缺失属性值进行补齐。大量实验证明了本算法的有效性。
An algorithm for completing the incomplete data table based on a novel harmonized valued tolerance relation is proposed in this paper. First of all, the algorithm determines the tolerance classes of the default objects with incomplete attribute value and quantifies the tolerance relation in combination with the attribute significance degree ,then completes the missing data on the premise of keeping as much as possible the harmony of the system according to decision rules independence principle. A great deal of experiments has proved the availability of this algorithm.
