振动诊断的特征评价和特征压缩

The Feature Assessment and Reduction of Vibration Diagnosis

本文结合实例应用模式识别理论分析了振动诊断时的特征评价和特征压缩问题,给出了具体结果。提出用加权的主分量分析法来处理特征分类能力的差别,达到优化信号特征的目的。

This paper deals with the feature assessment and reduction problems in vibration diagnosis by pattern recognition theory. A weighted principal component analysis procedure is proposed, and an example is given.
