Multiclass classification (6 classes): classes correspond to the condition of cultivation. S/P=1.55. Experimental details in Telagathoti et al. 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.",
