摘要:

在实践中,测试时的数据分布通常与原始训练数据的分布或多或少地不同。因此,在可用的标记数据上训练的所谓的源分类器在测试或目标数据上恶化。域自适应分类器旨在解决这个问题,但通常假设某种特定形式的域转移。大多数是不鲁棒违反域转移假设,甚至可能比他们的非自适应同行执行更差。我们构建了强大的参数估计判别分析,保证非自适应源分类器的自适应分类器的性能改进。

英文摘要:

In practice, the data distribution at test time often differs, to a smaller or larger extent, from that of the original training data. Consequentially, the so-called source classifier, trained on the available labelled data, deteriorates on the test, or target, data. Domain adaptive classifiers aim to combat this problem, but typically assume some particular form of domain shift. Most are not robust to violations of domain shift assumptions and may even perform worse than their non-adaptive counterparts. We construct robust parameter estimators for discriminant analysis that guarantee performance improvements of the adaptive classifier over the non-adaptive source classifier.
