Figure 3: Partial dependence plots for K.

Partial dependence curves are shown as solid black lines for: (a) volume per atom, (b) arithmetic mean of elemental row number, (c) cohesive energy, and (d) quartic-harmonic mean of elemental electronegativity. Training data points are shown in the background, colored per the descriptor indicated below each colorbar, to help illustrate the relationship between descriptors. The mean of the outcome (K) is shown as a thin dashed black line for reference.
