Robust Bayesian Satisficing
Distributional shifts pose a significant challenge to achieving robustness in
contemporary machine learning. To overcome this challenge, robust satisficing
(RS) seeks a robust solution to an unspecified distributional shift while
achieving a utility above a desired threshold. This paper focuses on the
problem of RS in contextual Bayesian optimization when there is a discrepancy
between the true and reference distributions of the context. We propose a novel
robust Bayesian satisficing algorithm called RoBOS for noisy black-box
optimization. Our algorithm guarantees sublinear lenient regret under certain
assumptions on the amount of distribution shift. In addition, we define a
weaker notion of regret called robust satisficing regret, in which our
algorithm achieves a sublinear upper bound independent of the amount of
distribution shift. To demonstrate the effectiveness of our method, we apply it
to various learning problems and compare it to other approaches, such as
distributionally robust optimization

Ankara : İhsan Doğramacı Bilkent Üniversitesi İktisadi, İdari ve Sosyal Bilimler Fakültesi, Tarih Bölümü, 2018.This work is a student project of the Department of History, Faculty of Economics, Administrative and Social Sciences, İhsan Doğramacı Bilkent University.The History of Turkey course (HIST200) is a requirement for all Bilkent undergraduates. It is designed to encourage students to work in groups on projects concerning any topic of their choice that relates to the history of Turkey. It is designed as an interactive course with an emphasis on research and the objective of investigating events, chronologically short historical periods, as well as historic representations. Students from all departments prepare and present final projects for examination by a committee, with 10 projects chosen to receive awards.Includes bibliographical references (page 21).by Merve Biçer
