Abstract
chemometric data analysis challenge has been arranged during the first edition of the
“International Workshop on Spectroscopy and Chemometrics”, organized by the Vistamilk
SFI Research Centre and held online in April 2021. The aim of the competition was to build a
calibration model in order to predict milk quality traits exploiting the information contained
in mid-infrared spectra only. Three different traits have been provided, presenting heterogeneous
degrees of prediction complexity thus possibly requiring trait-specific modelling
choices. In this paper the different approaches adopted by the participants are outlined and
the insights obtained from the analyses are critically discussed.
