Simultaneous identification of geographical origin and grade of flue-cured tobacco using NIR spectroscopy

Feasibility of an NIR spectral calibration transfer algorithm based on optimized feature variables to predict tobacco samples in different states

“…17,18 This allows for the variations in the physical properties and chemical composition of substances to be reected in real time. [19][20][21][22] Over the past few years, NIR spectroscopy has provided important guidance in the identication of geographical origin, 23 grade determination, 24 and detection of the chemical composition of tobacco. 25 A reliable multivariate calibration model is developed from the calibration set samples with known attribute measurements, followed by prediction of the unknown sample characteristics, while the accuracy of the prediction results is always strongly associated with the homogeneity of the samples.…”

Across different instruments about tobacco quantitative analysis model of NIR spectroscopy based on transfer learning

“…NIR spectroscopy is already extensively used in petroleum, 1 agriculture, 2 chemical, 3 tobacco, 4 food, 5,6 and pharmaceutical 7,8 industries since it is a simple, rapid, non-destructive, and reliable analytical method. However, due to the variability of measurement conditions ( e.g.…”
