Deep learning has the potential to revolutionize quantum chemistry as it is ideally suited to learn representations for structured data and speed up the exploration of chemical space. While convolutional neural networks have proven to be the first choice for images, audio and video data, the atoms in molecules are not
restricted to a grid. Instead, their precise locations contain essential physical
information, that would get lost if discretized. Thus, we propose to use continuous-filter convolutional layers to be able to model local correlations without requiring the data to lie on a grid. We apply those layers in SchNet: a novel deep learning architecture modeling quantum interactions in molecules. We obtain a joint model for the total energy and interatomic forces that follows fundamental quantum-
chemical principles. Our architecture achieves state-of-the-art performance for
benchmarks of equilibrium molecules and molecular dynamics trajectories. Finally,
we introduce a more challenging benchmark with chemical and structural variations
that suggests the path for further work.
