摘要
将变精度粗糙集(VPRS)理论引入到故障特征选择中,以分类质量作为启发知识设计了一种基于VPRS的故障特征选择方法,并通过一个实例验证了该方法的可行性。
Introduces VPRS theory into fault feature selection and presents a method for fault feature selection based on VPRS with classification quality as heuristic knowledge, the feasibility of this method is verified by an instance.
