The consistencies between LASP estimations, LASSO-MLPNet predictions, and the APOGEE_payne catalog. The red solid line and the green dashed line are dependencies of the MAEs between AOPGEE_payne catalog and LASSO-MLPNet predictions, and the MAEs between the AOPGEE_payne catalog and LASP estimations, on SNRg. The evaluation results of this experiment are calculated on test set 1 and test set 2.
