| 摘 要： | 针对构造决策树时，分类属性的选择直接影响分类效果的问题，提出了一种新的属性选择分类标准——集合分类粗糙度，该标准结合了ROUGH集知识表示与决策树构造的特性，能在总数不变的情况下，使叶结点的层次在一定程度上上浮．

| Abstract: | During constructing a decision, how to select classified attributes influences the effect of classification. This paper introduces a new way for selecting attributes, called Sets Classify Roughness, which is based on Rough sets theory and the characteristic of the decision tree and can elevate the level of leaf node to a degree when the total number does not change. |
