Improving Self-supervised Molecular Representation Learning using Persistent Homology

1 code implementation NeurIPS 2023 Yuankai Luo, Lei Shi, Veronika Thost

Self-supervised learning (SSL) has great potential for molecular representation learning given the complexity of molecular graphs, the large amounts of unlabelled data available, the considerable cost of obtaining labels experimentally, and the hence often only small training datasets.
