%description
Fairness-aware correction of a prediction model for binary and continuous
outcomes with two or more protected groups and their intersections. A
cross-fitted base learner (gradient-boosted trees or a neural network) is
fitted without the protected attribute, and a gated mixture of neural
experts learns a per-person correction to its score under a fairness
penalty (a random-effects or variance penalty on outcome-stratified group
means, or a thresholded worst-group penalty on error rates), with a
cross-fitted disparity signal, an intervention cost, smoothed early
stopping, a per-person export of adjustments with bootstrap stability
intervals, and routing analyses of which expert corrects whom. Methods
