Stochastic Regression Modeling of Chemical Spectra



Anthony J. Kearsley, William E. Wallace, Yutheeka Gadhyan


A stochastic regression method has been developed that decomposes chemical spectra into separate contributions from signal and from noise. The numerical results of regressing in this way on sample spectra are presented. The results suggest that this strategy offers an effective and efficient framework for in-depth noise estimation and analysis. From this analysis more effective means of feature extraction in chemical spectra can be created.
