Center node: "autoencoding undirected molecular graphs with neural networks"
  Abstract: We propose a machine learning model, inspired by language modeling from natural language processing, which can automatically correct molecules in discrete representations using a structure rule learned from a collection of undirected molecular graphs. Using discrete representations of molecules allows cheap, fast, and coarse grained insights. We introduce an adaption on a modern neural network architecture, the Transformer, which can learn relationships between atoms and bonds. The algorithm thereby solves the unsupervised task of recovering partially observed molecules represented as undirected graphs. This is to our knowledge, the first work that can automatically learn any discrete molecular structure rule with input exclusively consisting of a training set of molecules. In this work the neural network successfully approximates the octet rule, relations in hypervalent molecules and ions when trained on the ZINC and QM9 dataset. These results provides encouraging evidence that neural networks can learn advanced molecular structure rules and dataset specific properties, as the transformer surpasses a strong octet-rule baseline.
