“…The subinterval combination was selected on the basis of the combination of high accuracy of the joint model and a low RMSECV value. For the extraction of APIs, the optimal parameters of the SiPLS model were taken from the literature [ 25 ]. Each optimal SiPLS model was built by a combination of three subintervals taken from 20 equidistant subintervals.…”

“…mwPLS is a variable selection technique based on all continuous windows size "H" in the spectral data set. The RMSECV value of cross-validation was further used to find the best spectral region(s) of size H. Detail descriptions about iPLS and mwPLS theory and algorithms were reported in our previous references [8,9]. iPLS model performance did not perform significantly better than the full-spectrum PLS model in either of the two sampling modes (results not shown).…”

“…Due to the principle of overtones and combinations, it can gather information rapidly with little or no sample preparation. It has been widely used in the quantitative and qualitative analysis of Chinese herbal medicines (CHM) [5][6][7][8][9]. NIR has been widely regarded as an excel-lent online/in-line tool for process monitoring in CHM [10].…”

“…In the process of establishing a PLS model, spectral pretreatment methods have been applied to extract relevant information and reduce the effect of noise and baseline drift 8 9 . Variable selection is then also used to identify highly informative features and eliminate useless variables from the original spectral dataset 10 11 . The latent factors that explain the spectral matrix are sorted in decreasing order according to their contribution to the spectral features.…”
