Further analysis of the data obtained from ChEMBL33 revealed that numerous data points had a standard_value but no pchembl value. Although ChEMBL flagged these data points as "Outside typical range," we manually calculated the pchembl values aiming at investigating the model's performance both with and without them. After curation, they amounted to 307 additional data points labeled as "Outside typical range", 224 of which belonged to GABA transporters (Figure ). The curation process resulted in 6510 data points for the first data set with the automatically calculated pchembl values "auto" and 6817 data points for the second data set with the manually calculated pchembl values "manual".
