Presentation
Transferring a Molecular Foundation Model for Polymer Property Predictions
Presenter
DescriptionTransformer-based large language models have remarkable potential to accelerate design optimization for applications such as drug development and material discovery. Self-supervised pretraining of transformer models requires large-scale data sets, which are often sparsely populated in topical areas such as polymer science. State-of-the-art approaches for polymers conduct data augmentation to generate additional samples but unavoidably incur extra computational costs. In contrast, large-scale open-source data sets are available for small molecules and provide a potential solution to data scarcity through transfer learning. In this presentation, we discuss using transformers pretrained on small molecules and fine-tuned on polymer properties. We find that this approach achieves comparable accuracy to those trained on augmented polymer data sets for a series of benchmark prediction tasks.
