Researchers have developed a novel additive deep-learning framework designed to better predict aqueous solubility in drug discovery. This framework separates physicochemical descriptors, handled by a multilayer perceptron, from molecular graph topology, processed by a graph neural network. By combining these two information sources only at the prediction stage, the model offers a clearer understanding of whether solubility predictions are driven by global chemistry or molecular structure. The framework demonstrated improved accuracy and reduced variability when pre-trained on the larger AqSolDB dataset and fine-tuned on the smaller BigSolDB2 dataset, indicating robust feature learning.
