9. The method of claim 6 , wherein the first set of training data comprises a set of individual training examples, and wherein each example represents at least one molecule, and wherein each training example comprises a representation of the at least one molecule and a value for the property of interest modeled by each respective single target activity model.
9. The method of claim 6 , wherein the first set of training data comprises a set of individual training examples, and wherein each example represents at least one molecule, and wherein each training example comprises a representation of the at least one molecule and a value for the property of interest modeled by each respective single target activity model. 10. The method of claim 9 , wherein training a plurality of single target activity models, comprises: generating a form of each training example for use by a machine learning algorithm; and performing the machine learning algorithm using the set of individual training examples to generate a trained one of the more than three single target activity models.
