In recent years, intelligent condition-based monitoring of rotary machinery systems has become a major research focus machine fault diagnosis. monitoring, it is challenging to form large-scale well-annotated dataset due the expense data acquisition and costly annotation. The generated have large number redundant features which degraded performance learning models. To overcome this, we utilized ...
