Spectral Contrast Features: A Bin-Difference Approach to Interpretable, Parsimonious, and Cross-Instrument NIR Calibration
Near-infrared (NIR) spectroscopy with full-spectrum chemometric modeling is widely used in food, agricultural, and pharmaceutical analysis, but calibrations resting on hundreds to thousands of spectral variables are difficult to audit and require full-spectrum instrumentation to deploy. The Spectral Contrast Feature (S...
