Comparison of CNN prediction for the Gaia Benchmarks Stars (GBS). The reference T_eff, log(g), and [Fe/H] come from Jofré et al. (2018) and A(Li) from Guiglion et al. (2016). The GES-iDR6 values are also shown for comparison. On the x-axis, we present the GBS names sorted by increasing T_eff and on the y-axis, we present the four labels. The shaded region for each label represents the training set limits. The CNN predictions and error bars are mean of the estimates for the multiple spectra. CNN error bars are too small to be seen.
