Failed to show spectogram from three axis accelerometer

I tried changing the 3 axis accelerometer to a spectogram, but there is no pattern in the spectrogram and the value in the “Processed features” is zero as shown below

Someone can help me please?


Hello @Anya,

You can change the Noise floor (dB) parameters, you probabably need to decrease it to -120 or more, see the picture below.

However, I tried to train your model with your default parameters (as it is in your project) and it has a good accuracy.

Best regards,
