Longitudinal wastewater sampling in buildings reveals temporal dynamics of metabolites
Fig 7
Single-day feature profiles allow accurate building classification and uncover features with building-specific fTDs.
(A) ROC-AUC plot (true positive versus false positive rate) for the three one-versus-the-rest building comparisons, using individual days as data points with associated ion intensities as features. AUC plots and scores come from 50x repeated model training on randomized train-test data splits. (B) Putative identification (level 2) and log ion intensity time courses of four select, high-importance metabolites that contribute to model performance.
