摘要
含空值决策表的分析一直是智能信息处理领域的一个难点,论文讨论基于赋值容差关系的数据不完全的信息系统中的数据处理方法,并用实例说明不完全决策表中属性约简和决策规则的发现方法。
The analysis of decision table with missing values has been a key problem in the fields of intelligent information processing.In this paper,a novel approach to data processing based on valued-tolerance relation for incomplete information systems is given.An example is presented to illustrate the method of attribute reduct and decision rules acquisition in incomplete decision table.
