Their solution to a similar problem (i.e., errors relative to a CCSD(T)/CBS gas phase reference) was to use exact differences for small dipole moment species (≤1.0 D) and fractional differences for large dipole moment species (>1.0 D). While this does "regularize" the errors to some extent, it introduces an arbitrary transition in how to treat the differences at 1.0 D, a dipole moment that has no special physical meaning. Our solution to this problem is to multiply the residuals by a weighting function:
