Abstract: Traditional machine learning requires good tags to obtain excellent performance, while manual tagging usually consumes a lot of time and money. Due to the influence of domain shift, using the trained model on the source domain directly on the target domain is not good. Domain adaptation is used to solve the above problems. The deep domain adaptation method uses deep neural networks to complete domain adaptation. This article has carried out a comprehensive review of the deep domain adaptation method of image classification. The main contributions are the following four aspects. Firstly, we divided the deep domain adaptation into several categories based on the label set of the source domain and the target domain. Secondly, we summarized various methods of Closed-set domain adaptation. Thirdly, we discussed current methods of multi-source domain adaptation. Finally, we discussed future research directions, challenges, and possible solutions.
