Abstract:
1. A method for estimating a target analyte concentration from a test spectrum collected from a sample, the method comprising: accessing a first spectral data set that includes a plurality of spectra collected from first samples, the first spectral data set including a training data set of training spectra and a test data set of test spectra; accessing independently measured target analyte concentrations corresponding to the training spectra, the independently measured target analyte concentrations collected from second samples different than the first samples; generating modified measured target analyte concentrations from the independently measured target analyte concentrations by applying a delay model that converts concentrations from the second samples to corresponding concentrations from the first samples; generating a model that predicts target analyte concentration based on a test spectrum, the model generated based at least in part on the first spectral data set and on the modified measured target analyte concentrations; and applying the model to the test spectrum to estimate the target analyte concentration.
