Rough sets and fault diagnosis of rotating machine on rough set theory(III)——Forming decision rule and reduce
Xu Qi · Journal of Nanjing University · 2003
To rotating machinery fault artificial intelligence diagnosis rough sets is applied. On insufficient data, no hypothesis and no specialist's experience,reasoning is done under roughness unchanging, and decision be got in decision discernibility constant. Its rules are found out and credibility is provided. Attribute of knowledge base is reduced,and unwanted condition attribute and redundancy data are cleared up. The optimization decision table is formed.
