A Theory of Multiple-Source Adaptation with Limited Target Labeled Data
Proceedings of The 24th International Conference on Artificial Intelligence and Statistics, PMLR 130:2332-2340, 2021.
We study multiple-source domain adaptation, when the learner has access to abundant labeled data from multiple-source domains and limited labeled data from the target domain. We analyze existing algorithms for this problem, and propose a novel algorithm based on model selection. Our algorithms are efficient, and experiments on real data-sets empirically demonstrate their benefits.
