Table 2. Correlation Coefficient (R) of Protein–Protein and Protein–Ligand BA Predictors on the Test Set of 100 Protein–Peptide Complexesa.
method | R | MAE (kcal/mol) |
---|---|---|
PRODIGY | 0.13 | 1.9 |
DFIRE | 0.29 | 8.7 |
CP_PIE | –0.28 | 9.0 |
Kdeep* | 0.32 | 10.7 |
RF-Score* | 0.23 | 1.8 |
PPI-Affinity | 0.55 | 1.1 |
Protein–ligand methods are marked with a star. The negative values of the correlation coefficients indicate that the corresponding method predicts unbinding free energy.
