基于属性层次结构,定义了有效/无效对象,研究了判定有效/无效对象的相关理论与方法,给出生成所有有效/无效对象的缩减法,并就具有10个属性的属性层次结构,对其算法进行了线性回归.
Based on attribute hierarchy,a valid/invalid object was defined,and the algorithm of constructing all valid objects was given.Mathematical model with 10 attributes was built for the algorithm by linear regression analysis.
