Estimation results. (a) Estimation results for T_eff. (b) Estimation results for log g. The upper subplots in both figures show the kernel density plots of predicted values and true labels, with yellow areas indicating high-density regions. The lower subplots show the residual distribution between predicted values and true labels. The horizontal axis represents true labels, and the vertical axis represents residuals and predicted values. The red solid line represents the identity line.
