摘要
在系统相似性度量中特征分析的基础上,研究了特征选择的重要性,提出了相关特征对系统相似度量的影响,详述了利用相关分析法选择特征的方法和步骤,通过实例计算表明,用该方法选择出的特征进行系统相似度量能够较客观地反映出系统间实际的相似程度。
Based on the analysis of characteristics in measuring similar systems, the importance of characteristic selection is studied. The influence of system similarity measure because of correlation characteristics is presented. The process of selecting characteristics is elaborated. The method of characteristics selection is presented by citing an instance and computed result conform to objective reality.
