Method & Evidence

AimCan transformer models pretrained on small molecule data be effectively fine-tuned to accurately predict polymer properties, thereby mitigating data scarcity issues in polymer science?
MethodTransfer Learning and Fine-tuning
ProcedureA transformer-based model was first pretrained on a large dataset of small molecules using self-supervised learning. This pretrained model was then fine-tuned on a smaller dataset of polymer properties for specific prediction tasks. The performance of this transfer learning approach was compared against models trained solely on polymer data, including those augmented with additional samples.
