... hetero- geneous transfer learning relates to other types of learning, Figure 1 presents an intuitive illustration of four learning strategies, including traditional machine learning, transfer learning ... distributions, multi-view learning and hetero- geneous transfer learning. As we can see, an important distinguishing feature of heterogeneous transfer learning, as compar...
