Zenodo (CERN European Organization for Nuclear Research) June 8, 2026 Mehdi Belafekir
Across 6 datasets, 148 subjects, and 1,267 awakenings, 52 validation analyses found no evidence of above-chance generalization after bootstrap testing. Dataset identity accounted for 74.5% of predictive variance, indicating that models did not transfer across datasets. All code and data are publicly available.
