It seems that it is highly possible for me to get offers from Boston University, NTU and COSSE Program. Professor in NTU concentrates on data mining in video and the research direction of professor in Boston is network optimization.
But I don’t know how to make a choice now. Boston University is very close to Harvard and MIT. If I go to BU, I may be able to communicate with many prominiant professors more directly. However, the professor in NTU seems to be conscientious, andin my point of view, computer vision is more prospective than network optimization.
