All code implementing the above is open source, permissively licensed, and available online at github.com/JacksonBurns/fastsolv. (higher solubility in acetone), and accurately predicting the gradient of solubility with respect to temperature (Figure ). In contrast, the Vermiere model overpredicts the solubility in both acetone and isopropanol, exhibits much greater model uncertainty, and overpredicts the slope of the curve with respect to temperature. For L-prolinamide, we impose a challenging task for the model by predicting solubility in extremely similar solvents, hexane and heptane. We observe that fastsolv is able to discriminate solubility between these similar solvents, correctly predicting higher solubility in heptane, while the Vermiere model predicts identical soubility in both solvents (Figure ). Again, we also observe accurate absolute predictions, gradients, and lower model uncertainty.
