摘要
连续属性离散化是粗糙集应用研究的重点内容之一。基于条件熵可以反应属性依赖度的性质,将决策属性对条件属性的条件熵作为离散化标准,提出了一种粗糙集连续属性离散化方法,并通过实例证明了该方法的正确性。
The discretization of continuous attributes is one of the important contents in application study of rough sets.Based on the property that conditional entropy can reflect the attribute dependencies,taking conditional entropy of decision attributes to conditional attributes as the standard of discretization,a method of discretization of continuous attributes in rough sets is offered.And the method is proved right through actual example.
