Next, we turn our attention to the performance of the multitask models on reproducing relative energies over torsion scans on a set of small organic molecules. Here we compare single-task QRNN models trained solely to either the ANI-1x or ANI-ccx datasets to a multitask model trained to both and evaluated on the two output heads. Mean Absolute Deviations (MADs) of the relative energy over each torsion scan are computed for a subset of the dataset of Sellers et al. We restrict our attention only to molecules composed of the elements Hydrogen, Carbon, Nitrogen and Oxygen (HCNO), of which there are 45 examples in this dataset. Here, the reference energy is CCSD(T)/CBS and we utilize the reference geometries from Sellers. Figure shows that the behavior of the models trained to two datasets is slightly improved over single-task models trained to only a single dataset. The
