Predicted vs. measured VHT alteration rate for (a) PQM, (b) ANN, (c) LLR, and (d) GPR models, based on the same test samples from a single train-test split. The points are color-coded based on the density of the scatters on the plot (the concentration increases from blue to red), and * represents the unit of the scaled VHT alteration rate, i.e., g/(m2·d). The dashed line is added to visualize the perfect agreement.
