I am trying to extract some features of the accelerometer sensor and during the feature extraction each 5 second segment in the array is windowed and features are generated from these windows. Features extracted include: • Mean of the magnitude data • Maximum value. • Minimum value. • Standard Deviation value for each axis (x, y, and z). • Average Standard Deviation over 3 axes. • Root mean squared acceleration (RMS). • The sum of height of frequency component below 5 Hz. • Number of peaks in spectrum.
I am not sure if mixing all these is adding redundant values and affect the final results.
