Recent advances in machine learning have made significant contributions to drug
discovery. Deep neural networks in particular have been demonstrated to provide
significant boosts in predictive power when inferring the properties and
activities of small-molecule compounds (Ma, J. et al. J. Chem. Inf. MODEL: 2015,
55, 263-274). However, the applicability of these techniques has been limited by
the requirement for large amounts of training data. In this work, we demonstrate
how one-shot learning can be used to significantly lower the amounts of data
required to make meaningful predictions in drug discovery applications. We
introduce a new architecture, the iterative refinement long short-term memory,
that, when combined with graph convolutional neural networks, significantly
improves learning of meaningful distance metrics over small-molecules. We open
source all models introduced in this work as part of DeepChem, an open-source
framework for deep-learning in drug discovery (Ramsundar, B. deepchem.io.
