I have some labeled sensor data.

Now, I would like to know how to extract features from time series using DFT, DWT, and HAAR transforms.

I know that the transformations above transform a signal to frequency or time frequency domain, but how can I get average frequency for this non stationary signal?

Thanks.

Have you been able to transform your data? Or do you basically ask how to transform it? – Nikolas Rieble – 2017-03-18T12:09:43.170

I tried to edit your post but in the last sentence I got stuck! I changed "the" to "but" but I think it's still unclear what you want. – Kasra Manshaei – 2017-03-24T09:55:00.020

1Not sure why you would want to find an average frequency. What is your higher-level question you want to answer? What kind of sensor is it for which you have data? What is your sampling rate? – Adrian Keister – 2017-06-08T16:37:17.380
