Research on Method of Analog Circuit State Recognition Based on KPCA-SVDD

In order to improve analog circuit recognition, combined KPCA and SVDD, put forward one scheme of analog circuit state recognition based on KPCA-SVDD. Firstly distill characteristic of the outputs voltage signal by KPCA, taking the energy as the eigenvector of state recognition, Then adopt the SVDD categorize method to establish SVDD model of different state, carry on circuit state recognition, Finally with a certain electronic equipment filter circuit for example, verified the usefulness of the method.
