Figure 6. Comparison of predicted vs. true values of hydroxide conductivity (mS/cm) for PS and CS datasets using ST and MT models for a single instance of 80% training data and 20% testing data. (A) and (B) represent ST and MT predictions for the PS dataset, while (C) and (D) represent ST and MT predictions for the CS dataset. The diagonal dashed line indicates the ideal case in which predicted values perfectly match the true values. The RMSE and R² values for each model are provided, demonstrating improved predictive performance with the MT models in both the PS and CS splits. The error bars represent prediction uncertainty, highlighting the increased confidence of the MT model. PS: Polymer split; CS: composition split; ST: single-task; MT: multi-task; RMSE: root mean squared error; R²: coefficient of determination.
