| Abstract(in English) | We consider the problem of domain adaptation under the target shift scenario, where the target marginal distribution p(y) changes between the training and testing phases, while the target-conditioned covariate distribution p(x|y) remains unchanged. Although various methods for mitigating target shift in classification (a.k.a. class-prior change) have been developed so far, few methods can be applied to continuous targets. In this paper, we propose methods of continuous target shift adaptation in regression and conditional density estimation. More specifically, our contribution is a novel importance weight estimator for continuous targets. Through experiments, the usefulness of the proposed methods is demonstrated. |
