A Novel Feature Enhancement Method Based on Improved Constraint Model of Online Dictionary Learning

Online dictionary learning (ODL) is an emerging and efficient dictionary learning algorithm, which can extract fault features information of fault signals in most occasions. However, the typical ODL algorithm fails to consider the interference of noise and the structural features of the fault signal...
