Comparison between neural network stellar mass estimates obtained from LAMOST spectra and the corresponding reference masses. Left panels: scatter-density diagrams showing NN-predicted masses versus Gaia-based masses (top) and versus MSTO masses (bottom). Right panels: histograms of the relative percentage error between the NN and reference masses, given by (NN mass – reference mass)/reference mass × 100%.
