The methodological errors in Vermeire et al. model training lead to overly optimistic performance results reported in this study as shown in Figure . As shown in the solute Venn diagrams in Figure , many entries in the SolProp testing set are present in the training set. In evaluating Vermeire et al.'s performance on the rigorous solute extrapolation test posed by the Leeds set, the performance drops to RMSE = 2.16, demonstrating a more realistic test performance. Additionally, we observe nonphysical gradients with respect to temperature, indicating the model has not learned a functional approximation of the temperature dependence of log S.
