AI3SD Video: Preserving Structural Motifs in Machine-Learning Approaches to Modeling Water Clusters
Chemical structures are naturally viewed as collections of atoms connected through bonds, and graph theory provides a natural tool for capturing that intuition in a concrete mathematical fashion. Over the past several years, graph neural networks have become increasingly popular for modeling chemical systems. To build on this work, the multi-laboratory ExaLearn project, part of the DOE Exascale Computing Project, is developing novel capabilities that combine state-of-the-art machine-learning techniques with high-performance computing to enable the rapid exploration of chemical space on exascale-class systems. Water clusters offer an interesting use case for the development of machine-learning approaches that preserve intermolecular interactions and structural motifs. We apply a dataset of ~5 million hydrogen-bonded water clusters that display interesting long-range structural patterns to explore unique challenges in property prediction and molecular generation.

Abstract
Chemical structures are naturally viewed as collections of atoms connected through bonds, and graph theory provides a natural tool for capturing that intuition in a concrete mathematical fashion. Over the past several years, graph neural networks have become increasingly popular for modeling chemical systems. To build on this work, the multi-laboratory ExaLearn project, part of the DOE Exascale Computing Project, is developing novel capabilities that combine state-of-the-art machine-learning techniques with high-performance computing to enable the rapid exploration of chemical space on exascale-class systems. Water clusters offer an interesting use case for the development of machine-learning approaches that preserve intermolecular interactions and structural motifs. We apply a dataset of ~5 million hydrogen-bonded water clusters that display interesting long-range structural patterns to explore unique challenges in property prediction and molecular generation.
