In this case humans are doing the job of transferring from D to D∗, and the training algorithm just has to generalize from a representative sample of D∗ to the test set.
Thank you, this was helpful. I hadn’t understood what was meant by “the generalization is now coming entirely from human beliefs”, but now it seems clear. (And in retrospect obvious if I’d just read/thought more carefully.)
