I collected data from a motor at different RPMs creating different labels for a balanced state.
Similarly, collected data at same as previous RPMs by creating imbalance in the motor.
At each RPM, I have collected 10s data at 100 Hz sampling frequency 5 sets in balanced condition and unbalanced condition.
I trained the network using spectral features, but it took 18 classes instead of 2 ( each having 9 RPM states with 5 sets of data ) leading poor accuracy.
Now i would like to merge the data of all RPMs belongs to
Pls suggest me how to merge data.
