a The total stress prediction combines the predictions of the trend stress model with the model for oscillations. The trend part of iTF-DNN is trained from the observed measurements. The residuals (b) of the trend part of iTF-DNN are transformed with an STFT to the time-frequency domain (c) and further used to train the oscillation part of iTF-DNN.
