116(Y/Yn)^1/3-16. The exponent 1/3 is omitted in the published text. In addition, the leading factor in the expression for b* should be 200 rather than 500. 3) In the expression for "deltaH*_94" just above Eq. 5.8, each term inside the radical should be squared.

We propose a method to improve the prediction performance of existing color-difference formulas with additional visual data. The formula is treated as the mean function of a Gaussian process, which is trained with experimentally determined color-discrimination data. Color-difference predictions are calculated using Gaussian process regression (GPR) considering the uncertainty of the visual data...
