Prediction accuracy by GPCR family for the first experiment
| Family\Ktar | Dirac | multitask | hierarchy | BP | PBP |
| Rhodopsin peptide receptors (18) | 73.7 | 80.0 | 85.8 | 83.8 | 83.7 |
| Rhodopsin amine receptors (35) | 91.1 | 92.1 | 94.0 | 93.9 | 94.1 |
| Rhodospin other receptors (17) | 83.6 | 88.0 | 95.7 | 95.9 | 95.9 |
| Metabotropic glutamate family (9) | 73.1 | 93.5 | 98.9 | 83.3 | 93.3 |

Mean prediction accuracy for each GPCR family for the first experiment with the 2D Tanimoto ligand kernel and various target kernels. The numbers in bracket are the numbers of receptors considered in the experiment for each family. BP is the binding pocket kernel and PBP the poly binding pocket kernel.
