Results of the testing set for various astrophysical parameters (T_eff, log g, [Fe/H], α/M, [Mg/Fe]) obtained in this study using the NN model. Each plot features a one-to-one correlation between the parameters obtained from APOGEE, GALAH, and LAMOST surveys and those predicted by the NN, with identity line included for reference. Blue and red dots correspond to dwarfs and giants, respectively. For both dwarfs and giants, the colorbar indicates the T_eff. The size of the symbols represents the value of log ɡ.
