摘要
探讨了基于变精度粗糙集模型的故障诊断规则获取方法,该方法通过相应的变精度属性约简算法,利用变精度属性约简有效地处理带噪声的决策表,提取符合可信度要求的故障诊断规则形成规则集。此方法克服了标准粗糙集模型对数据噪声过于敏感的缺点,增强了数据分析和处理的鲁棒性。
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 applications show that this method overcomes sitive to the noise. This method also strength diagnosis rule that is suit for confidence requirement. The the shortcoming about which standard rough set model is too senens the robustness of data analysis and procegs.
