Integrating physics in deep learning algorithms: a force field as a PyTorch module.

Abstract

Deep learning algorithms applied to structural biology often struggle to converge to meaningful solutions when limited data is available, since they are required to learn complex physical rules from examples. State-of-the-art force-fields, however, cannot interface with deep learning algorithms due to their implementation. We present MadraX, a forcefield implemented as a differentiable PyTorch module, able to interact with deep learning algorithms in an end-to-end fashion. MadraX documentation, together with tutorials and installation guide, is available at madrax.readthedocs.io.
