ELSA efficiently adapts to label shift without post-prediction calibrations.

problem Domain adaptation with label shift across training and testing datasets.
method Moment-matching framework based on influence function geometry; solves linear systems for adaptation weights.
result ELSA estimator is n\sqrt{n}-consistent and asymptotically normal, achieving state-of-the-art estimation performance.
