“…SPA is a novel variable selection method that aims at eliminating the redundant information of raw spectral data to the biggest extent. As a forward selection algorithm, it is put forward to achieve the minimum of vector space collinearity by successive orthogonal projection [22,23]. The number of eventual feature variables could be decided, according to the minimal root mean square error of validation (RMSEV) in multiple linear regression calibration.…”

“…by their non-destructive nature, no need of sample preparation and toxic reagents, low cost and reproducibility. In this context, fluorescence and UV-VIS spectroscopy have been successfully used for the development of multivariate calibration models based on PLS and MLR methods to quantify potential adulterations in extra virgin olive oil(Milanez, et al, 2017). The fluorescence data attributed to phenolic compounds and tocopherols (300-390 nm), oxidation products of fatty acids (445-475 nm), vitamin E (525 nm), and degradation products of chlorophyll a and b (681 nm) were used as predictors.…”
