| "description": "PTR-ToF-MS fungal species classification: 593 measurements and 383 peaks from 25 biological strains of six species, measured in pure culture and co-culture with Pseudomonas helmanticensis (Probst et al., Scientific Reports 2023). Labels 0-5 correspond to Entomortierella galaxiae, Linnemannia exigua, L. hyalina, L. sclerotiella, L. gamsii and L. solitaria. Five strain-grouped outer folds test every measurement once. The three requested inner folds reduce to two in each outer fold because of limited class support at the strain level. The final-fit validation holdout is also strain-disjoint. Sample, strain and condition identifiers are metadata, not features. Source PTR-ToF-MS peak values are area-normalized to a row sum of one and are retained without an additional logarithmic transformation. Feature scaling is fitted within each training partition.", |
