Review for NeurIPS paper: Ensuring Fairness Beyond the Training Data

Additional Feedback: 1- Perhaps the reviewer missed it, but was is "f" in Eq (1) onwards? Is f(x,a) the same as h(x,a) -- which is defined in line 80? 2- The statement in the text immediately after Eq (1) seems incorrect. DP is supposed to be the difference in "acceptance rate" of the two groups a and a'. This would also make sense assuming that f() returns the predicted label. For instance, some discussion is needed into the drop in accuracy for the Robust classifier.
