Characteristic signals in rotating machinery fault diagnosis with the issues of complex and difficult to deal with, while the use of non-linear manifold learning method can effectively extract low-dimensional manifold characteristics embedded in the high-dimensional non-linear dataIt greatly maintains the overall geometric structure of the signals and improves the efficiency and reliability of the rotating machinery fault diagnosisAccording to the development prospects of manifold learning, this paper describes four classical manifold learning methods and each advantages and disadvantagesIt reviews the research status and application of fault diagnosis based on manifold learning, as well as future direction of researches in the field of manifold learning fault diagnosis.
