Robust Active Learning

  • Author / Creator
    Nie, Rui
  • This dissertation first introduces the concepts of robust active learning (also called optimal experimental design in statistics), and the possible advantages of it over the traditional passive learning method. Then a general regression problem with possibly misspecified models is presented, and divided into three specific problems due to different choices of loss functions and optimizing methods. After that, the three problems are all solved with a minimax approach but in different ways to get the optimal design densities for the active learning method. Finally, simulations are used to compare active learning with passive learning results on specific examples, and the experiment results prove that active learning is more robust and advantageous than passive learning in these examples.
