Lastly, for Experiment 11, we utilized an entirely different pKa dataset provided at , which we will call CZO. This dataset utilizes a training set composed of a combination of pKa data from ChEMBL25 and DataWarrior 17 containing a total if 5904 molecules. Also provided are two test sets, one available from AvLiluMoVe 18 containing 123 molecules and the other provided by Novartis containing 280 molecules. Each of these test sets are distinct from the training data. When training our models, we again normalized each datasets to have zero mean and unit variance. In order to perform Experiment 11, we randomly selected 10
