Physical parameters derived using RF, assuming S/N = 10 at z = 0.3. Top: results for the mwa (left), uwa (centre), and metallicity (right). Bottom: sSFR, A_V, and t_mod/τ, from left to right. Each sub-panel on the bottom shows the difference between predicted and true values (Δx). The blue lines show the bias estimated using moving averages. Similarly, the lime-green lines show the σ. The red line shows the one-to-one line (top sub-panels) or 0 value (bottom sub-panels). Finally, the colour bar shows the number of galaxies in the density plot.
