Illustration of compression factors τ(x) for each transformation function Mathematical equation obtained via three different warping strategies: (a) physics-based relationship between energy and wavenumber, (b) signal-smoothness-based warping, (c) hybrid combination of both. The compression factors illustrate how the input energy grid x is stretched and compressed for a given XAS spectrum.
