Can a zero-shot time-series foundation model rival task-trained models for intraoperative hypotension prediction? A two-cohort benchmark and the role of covariate-awareness
This study demonstrates that zero-shot time-series foundation models, particularly TiRex-2, can rival task-trained baselines in predicting intraoperative hypotension across diverse cohorts, offering a portable alternative that maintains high accuracy without requiring site-specific training or drug-infusion covariates.
