Webb11 apr. 2024 · PLSR models were developed using different preprocessed spectral data as input variables. The results of the PLSR models based on the raw and preprocessed data are shown in Table 1. For Cd prediction, the optimal performance with an R cv2 of 0.950 and RMSECV of 7.294 mg/kg was obtained using the spectra preprocessed with MSC.
