A hybrid approach of symbolic aggregate approximation and bitmap: application to fault diagnosis of reciprocating compressor valve

Feature extraction plays an important role in machinery fault diagnosis and prognosis. The features extracted from time, frequency and time-frequency domains are widely investigated to describe the properties of overall signal from different perspectives (e.g. RMS, energy, etc.), seldom considering...
