| Abstract: | Domain adaptation learning aims to solve the learning problem of target domain by using the labeled samples of source domain.The key challenge is how to minimize the distribution distance among different domains at most and solve the change of data distribution effectively.Domain adaptation learning algorithms were summed up and classified.The characteristics of each type learning algorithm were summarized.Five typical algorithms were carefully analyzed and their performances were compared.What directions are worthy of further exploration was indicated. |

| Keywords: | Domain adaptation learning Maximum mean discrepancy Instance weighting Feature mapping |
