Accuracy of the ANN. For each object in the blind sample (5000 models), we estimated the difference between the SED from DIAD and the SED predicted by the ANN at each wavelength. We then estimated the 68% (1-σ), 95% (2-σ), and 99.9% (3-σ) percentiles. The yellow line corresponds to the median difference between DIAD and the ANN at each wavelength. Bottom plot: zoom to the −25% to 25% range.
