| "description": "PTR-ToF-MS analysis of chewing gum base material (267 samples, 167 peaks, 27 batches of technical replicates). Regression: predicted value is the percentage concentration of component 1 in the base material formulation. S/P=1.60. Features are standard-scaled (StandardScaler). 5-fold cross-validation splits are batch-aware: all samples sharing the same measurement batch (IDs field) are kept together in the same fold to prevent data leakage from technical replicates and batch effects.", |
