We show that signal processing provides a natural framework for separating structure across scales, enabling us to 1) disentangle scale-speciﬁc information in existing embeddings and 2) train models to learn more about particular scales. signal from Figure 2 above where there are two different signals at different amplitudes, you can see that the most prominent spike corresponds to the frequency of the highest voltage sine signal.
