The first panel compares the t_1/2 predictions with the actual values for the test dataset using a linear model based solely on the magnitude gap M₁₂. The second and third panels show the linear model predictions when additional observable properties from Tables 2 and 3 in Section 2 are incrementally included, namely M_BCG/M_sat and M₁₄, along with M₁₂. The second panel presents predictions analysis from a linear model using M_BCG/M_sat along with M₁₂. Similarly, the third panel show predictions analysis based on M_BCG/M_sat and M₁₄, respectively, combined with M₁₂. In the right column, we show the usual scatter and contour density plots comparing the predicted and actual t_1/2s, while the histogram of relative errors is displayed on the right side. We also present the relative error histogram for CNN Model 2, which provides the best balance between median relative error bias (positive median bias) and scatter among the three CNN models. This is for comparing the performance of the linear models with that of the CNN models.
