Table 5 Multi-valued mapping matches for the BP, HR and RWAT prediction tasks. For the BP task, there was a high match rate for both within the same patient records and across patients, suggesting an ill-conditioned problem. For the HR and RWAT tasks, the matches were much lower. Ground truth for RWAT is only available for the Aurora-BP dataset.
