DOI: 10.13232/j.cnki.jnju.2015.04.009, PP. 714-722
Keywords: 粗糙集,不确定性度量,条件熵,互信息
Abstract:
不确定性度量是粗糙集理论中的重要研究内容之一，它可以度量属性之间的依赖度和相似度，并为属性约简和聚类分析提供了有效的度量工具.然而，不同的不确定性度量对于属性依赖度和相似度的刻画能力并不相同，这将会很大程度上影响属性约简和聚类分析等算法的结果对常见的属性依赖度度量近似分类精度、近似分类质量、shannon条件熵、互补条件熵和常见的属性相似性shannon互信息、互补条件熵在不确定性度的差异进行了深入分析，发现了这些度量之间的差异，为属性约简和聚类分析等算法中不确定度量的选择提供了理论依据
