On the Hardness of Unsupervised Domain Adaptation: Optimal Learners and Information-Theoretic Perspective
On the Hardness of Unsupervised Domain Adaptation: Optimal Learners and Information-Theoretic Perspective arXiv:2507.06552v1 Announce Type: new Abstract: This paper studies the hardness of unsupervised domain adaptation (UDA) under covariate shift. We model the uncertainty that the learner faces by a distribution $pi$ in the ground-truth triples $(p, q, f)$ — which we call a UDA…
