Abstract
To deal with the issue of generalization ability affected by redundant information in the relevance vector ma⁃chine(RVM)based fault diagnosis model of transformers,this paper proposes a comprehensive fault diagnosis model based on the combination of neighborhood rough set(NRS)and RVM. First,neighborhood information and quick re⁃duction algorithm are employed to reduce the attribute reduction. Then,the dependence of conditional attribute on deci⁃sion attribute is used to acquire the attribute weight. Next,the feature vector set obtained after reduction and numeral⁃ization is input into the RVM for training. Finally,tests are conducted with test set. A case study shows that the diagno⁃sis rate with the proposed method is higher than the RVM model,which further indicates that NRS enhances the practi⁃cability and accuracy of RVM.关键词
