Outlier detection in rotating machinery under non-stationary operating conditions using dynamic features and one-class classifiers

The main goal of condition-based maintenance is to describe the machine state under current operating regimes, which can be non-stationary depending of load/speed changes. Besides, damaged machine data are not always available in real-world applications. This paper proposes a methodology of outlier...
