Researchers have developed a new method for selecting optimal wavelengths in near-infrared spectroscopy, crucial for improving the accuracy and interpretability of spectral data in tasks like sugar content estimation. This approach frames wavelength selection as a binary black-box optimization problem, utilizing Bayesian optimization with Thompson sampling to identify relevant wavelength regions. Experiments demonstrate that this combinatorial Bayesian optimization method outperforms genetic-algorithm-based selection and simulated annealing in partial least squares regression, yielding more consistent and robust wavelength selections.
