报告摘要:

It is well-known that the performance of a classifier / detector trained on one dataset will be degraded when applying on another dataset. It is called the dataset - bias problem. Domain adaptation has been proved to be an effective approach to solve the dataset-bias problem. Without labels in the target domain, many existing unsupervised domain adaptation methods assume that conditional distributions in source and target domains are equal to each other, so that the joint distributions can be aligned by matching the marginal distributions. However, it may not be able to verify whether such assumption is valid in practice. In this talk, I will briefly review the basic principle of domain adaptation. Then, I will report our recent research works on unsupervised domain adaptation for person re-identification and object recognition without using the equal conditional distribution assumption.
