Comparison between the real SFR values (TNG300, x-axis) and the ones predicted by the RF (y-axis) for the validation sample at z = 1 using one of the best three models with three subhalo properties (bottom) and the model with only V_peak (top). Blue lines show the SFR values that define SFR-selected number densities of $\overline{n}={10}^{-2}{h}^3{\mathrm{Mpc}}^{-3}$ and 10^−2.5 h³ Mpc⁻³ for the TNG300 values. Circles with error bars indicate the median, 16^th, and 84^th percentiles, which are only calculated when the number of points in a 0.4 dex bin is larger than 1000. The dashed green line indicates x = y. The term $\overline{\mathrm{\Delta }}$ is the mean deviation between the real and predicted values, and it is calculated in log scale using all the subhalos with log(SFR) > 0 and assuming SFR = 10⁻⁴ M_⊙/yr for quenched galaxies.
