Deep transfer learning (DTL), which incorporates new ideas from deep neural networks into (TL), has achieved excellent success in computer vision, text classification, behavior recognition, and natural language processing. As a branch of machine learning, DTL applies end-to-end to overcome the drawback traditional that regards each dataset individually. Although some valuable impressive general surveys exist on TL, special attention recent advances are lacking. In this survey, we first...
