Fractional-order Savitzky–Golay filter for pre-treatment of on-line vis–NIR spectra to predict phosphorus in soil

Mineral oil emulsion species and concentration prediction using multi-output neural network based on fluorescence spectra in the solar-blind UV band

“…In this study, the fluorescence signals obtained were weak and had a low signal-to-noise ratio. 28 Therefore, the S–G filter was chosen as the smoothing and processing algorithm, which is superior to the moving average smoothing algorithm.…”
