Optimal transport for conditional domain matching and label shift

چکیده
We address the problem of unsupervised domain adaptation under setting generalized target shift (joint class-conditional and label shifts). For this framework, we theoretically show that, for good generalization, it is necessary to learn a latent representation in which both marginals distributions are aligned across domains. sake, propose learning that minimizes importance weighted loss source Wasserstein distance between marginals. proper weighting, provide an estimator proportion by blending mixture estimation optimal matching transport. This comes with theoretical guarantees correctness mild assumptions. Our experimental results our method performs better on average than competitors range problems including digits,VisDA Office.

Domain Adaptation under Target and Conditional Shift
Let X denote the feature and Y the target. We consider domain adaptation under three possible scenarios: (1) the marginal PY changes, while the conditional PX|Y stays the same (target shift), (2) the marginal PY is fixed, while the conditional PX|Y changes with certain constraints (conditional shift), and (3) the marginal PY changes, and the conditional PX|Y changes with constraints (generalize...
متن کاملOptimal Shift-Or String Matching Algorithm for Multiple Patterns
In this paper, we develop a new algorithm for handling multiple patterns, which is based on average optimal shift-or algorithm. We have assumed that the pattern representation fits into a single computer word and length of each pattern is equal. We have adopted the concept of classes of characters for handling multiple patterns. We compare the performance of the proposed algorithm with the stan...
متن کاملLabel Distribution Learning by Optimal Transport
Label distribution learning (LDL) is a novel learning paradigm to deal with some real-world applications, especially when we care more about the relative importance of different labels in description of an instance. Although some approaches have been proposed to learn the label distribution, they could not explicitly learn and leverage the label correlation, which plays an importance role in LD...
متن کاملa benchmarking approach to optimal asset allocation for insurers and pension funds
uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
