Fractional distance errors and residuals of CNN predictions compared to labeled values from ASPCAP parameters, shown as a function of stellar properties. The residuals are calculated as the predicted values minus the labeled ones. The left three panels show the fractional distance error vs. three ASPCAP stellar parameters, color-coded by geometric distance. The gray dots with error bars represent the mean and standard deviation of the error in each bin. The right three panels show the residuals of Teff, log ɡ, and [Fe/H] vs. the ASPCAP values, color-coded by S/Ng (gray for spectra with S/Ng ≤ 100 and black for spectra with S/Ng > 100). The projected residual distributions are shown on the right.
