Figure 5. Comparison of MSE for training and test sets in the ANN model using FPS (yellow) and RS (blue) across various training sizes on physicochemical datasets. These datasets include the HVAP, CT, CV, and CP. MSE: Mean squared error; ANN: artificial neural network; FPS: farthest point sampling; RS: random sampling; HVAP: enthalpy of vaporization; CT: critical temperature; CV: critical volume; CP: critical pressure.
