These techniques mainly include change detection (CD) algorithms, independent component analysis, time-frequency analysis, energy concentration evaluation, as auxiliary tools for feature extraction and analysis of vibration signals. They operate in a reduced dimension space, highlight and enhance the changes in signals. Finally, the paper presents a case study in health status monitoring of an industrial pump.engeneral approachchange detectionindependent component analysistime-frequency analysisvibration signal processingmachine health monitoringConference paperhttps://ieeexplore.ieee.org/document/9136129
