Researchers have developed a novel Bayesian framework that combines spectral deconvolution with a model of expert scientific reasoning to improve peak estimation in spectral data. This approach integrates physical-property regression, using Gaussian process regression, with Bayesian spectral deconvolution to select spectral models based on their consistency with independently measured physical properties. The method has demonstrated success in recovering meaningful peak structures from noisy synthetic spectra and infrared spectra of poly(lactic acid), particularly for weak peaks related to degradation rates, outperforming conventional methods that rely solely on spectral information.
