Fluorescence spectroscopy is the preferred technique to monitor DBPs . Fluorescence spectroscopy is sensitive in assessing the characteristics and reactivity of NOM because of its minimal sample preparation requirement and short acquisition time . However, the complex high-dimensional characteristics of without extensive data pre-processing . Compared with multilayer perceptron (MLP) and dimensionality reduction techniques, CNN not only exhibits superior prediction accuracies for THMs and HAAs but also identifies the fluorescence spectra regions highly associated with DBP formation.
