Table 2.
The generalization performance based on correlation score (R), coefficient of determination (Q2) and mean absolute error (MAE) for different experiments. *** means that the value was not meaningful, because Q2 values were below −100 and MAE values were above 100. The values are averages across 100 CV runs. The values in parentheses show the standard deviations across 100 CV runs. RAVLT-Immediate is abbreviated as RAVLT-IR and RAVLT-Percent Forgetting is abbreviated as RAVLT-PF.
