We further compared the predictions of the new MLP and the original MLP model. The results of these predictions of the adsorption of real molecules from both models are shown in Table . The new MLP model, trained on 57.5% less data than the original MLP model, exhibited a comparable performance to the original MLP model. A similar level of performance by both MLP models was maintained for molecules within and outside the alchemical range. These results show that AL is useful in scaling down on the training data required by MLP models.
