A Fault Diagnosis Method based on SVM and DDAG for A Navigation Device

摘要

Support vector machine is a kind of promising ways for fault diagnosis. When it is expanded with multiclassification by using the decision directed acyclic graph, the problem of diagnosing the multiclassification fault of SVM can be solved. This article argues that SVM of multi-classification expanding by this method achieves a good diagnosing effect in the practice of applying in a type of navigation device.
