Adapting models further improved performance: (1) self-supervised finetuning by 3. 2% for AUROC and 1. 5% for AUPRC; (2) semi-supervised finetuning by 1. 8% for AUROC and 2% for AUPRC, compared to self-supervised finetuning; (3) foundational modelling by 3. 6% for AUROC and 2. 6% for AUPRC, compared to self-supervised finetuning.
