Evaluation of the emulator performance. The test performance is summarized in the top left panel, which shows a histogram of the test errors; specifically, the MFE (see Eq. (7)) is displayed. The other panels provide a direct comparison between emulated and simulated spectra for a subset of the test data. Each panel contains a histogram of the test errors, in which the position of the current model is highlighted. To highlight the subtle differences between the predicted and true spectra, the fractional difference ΔL/L is shown in the lower section of each panel (solid blue line). In both sections, the shaded regions indicate the 68% and 95% confidence intervals for the prediction of the emulator.
