Fig. 6From: Machine learning for a rapid discrimination of ginseng cultivation age using 1H-NMR spectraThe schematic workflow for the classification of ginseng cultivation age. Powdered ginseng samples were analysed using HR-MAS NMR. And acquired 1H NMR spectra were preprocessed. After data preprocessed, deep learning was used to make a prediction model for classifying ginseng cultivation age. When new data is available, deep learning model is retrained and updatedBack to article page
