I am trying to implement a way to use sparse filtering or another similiar algorithm to extract features directly from raw vibration signals. I tried the algorithm:
sparsefilt
But the results were not great. Maybe because this algortihm doesnt like to take raw signals as input (but wants already features?)
Also I have to mention that I am aware of this method:
https://de.mathworks.com/help/predmaint/examples/Rolling-Element-Bearing-Fault-Diagnosis.html
But my task is to find a way to exract features more automatic.
Can somebody help me to find the right algorithm to extract features from raw vibration signals?
Best regards

Same problem met.
Maybe Try PCA or ICA methold.
