In addition, the output of the MPNN was concatenated with precomputed molecular descriptors before the FFN. We denote this model MPNN+ in Table . Furthermore, a method based on a fingerprint-descriptor combination, which we donate ECFP2+, showed exceptional performance in the original study. ECFP2+ is a feed-forward neural network that takes ECFP fingerprints with radius r = 2 concatenated with precomputed molecular descriptors as an input.
