Improving the transfer ability of calibration model for terahertz spectroscopy

Inter-instrument variability and measurement condition changes pose great challenges for the maintenance of terahertz calibration models. The predictive accuracy of the trained calibration models is questionable for newly measured data sets. Obviously, this problem may hinder practical applications of terahertz spectroscopy. To tackle this problem, for the first time we explore to improve the transfer ability of calibration model for terahertz …
