Comparison with traditional methods in predicting log g and T_eff of white dwarfs. The first row shows the predictions for T_eff, while the second row displays the predictions for log g. The first column compares our results with those of Guo et al. (2015), using data from LAMOST. The second column compares our results with those of Kepler et al. (2021), using data from SDSS. The scatter point density in the yellow region is higher than in the purple region. The red solid line represents the identity line. The scatter points are distributed around the identity line, indicating that the predictions of EstNet are consistent and effective compared to traditional methods.
