| "description": "Retrospective four-group classification of healthy controls, skin-cancer controls, limited-radiation-toxicity controls, and acute-radiation-toxicity cases. The 171 gene-expression profiles represent 57 donors, each measured in donor-derived lymphoblastoid cells under mock, ultraviolet, and ionizing-radiation conditions (GEO GDS968/GSE1725; Rieger et al., PNAS 2004). Five donor-grouped outer folds test every profile once; three donor-grouped inner folds select hyperparameters. The final-fit validation holdout is also donor-disjoint. Donor and GEO sample identifiers are split metadata, not features.", |
