Method of Machinery Fault Diagnosis Based on Variable Precision Rough Set
Zhang Yin-li · Coal Mine Machinery · 2007
The rule acquisition method of fault diagnosis based on variable precision rough set is discussed.The method forms the rule set.With corresponding attribute reduction arithmetic,decision table that contains noise is dealed with efficiently,and then acquire the fault diagnosis rule that is suit for confidence requirement.The applications show that this method overcomes the shortcoming about which standard rough set model is too sensitive to the noise.This method also strengthens the robustness of data analysis and process.
