Regression: predicted value is the roasting time. S/P=0.19. Experimental details in Mazzucotelli 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.",
