Title: Modelling molecules and materials with atomic neural network

Abstract: Atomic neural networks (ANNs) constitute a class of machine learning methods for predicting potential energy surfaces and physio-chemical properties of molecules and materials.  Recently, we have taken the initiative and developed an open-source Python library named PiNN (, allowing researchers to easily develop and train state-of-the-art ANN architectures for making chemical predictions. In particular, we designed and implemented an interpretable and high-performing graph convolutional neural network architecture PiNet, and demonstrated how the chemical insight “learned” by such a network can be extracted (Shao Y., Hellström M., Mitev P.
