      Fabretti, A.; Herzel, S.; Pınar, M. Ç. (2014)
      We examine the problem of setting optimal incentives for a portfolio manager hired by an investor who wants to induce ambiguity-robust portfolio choices with respect to estimation errors in expected returns. Adopting a ...
    • Diversity and novelty in information retrieval

      Santos, R. L. T.; Castells, P.; Altingovde, I. S.; Can, Fazlı (Association for Computing Machinery, 2014-02)
      This tutorial aims to provide a unifying account of current research on diversity and novelty in the domains of web search, recommender systems, and data stream processing.
    • Essays on bilateral trade with discrete types 

      Mohammadinezhad, Kamyar Kargar (Bilkent University, 2019-11)
      Bilateral trade is probably the most common market interaction problem and can be considered as the simplest form of two sided markets where a seller and a buyer bargain over an indivisible object subject to incomplete ...
    • Optimal allocation with costly inspection and discrete types under ambiguity 

      Bayrak, H. I.; Güler, K.; Pınar, M. Ç. (Taylor & Francis, 2017)
      We consider the following problem: a principal has a good to allocate among a collection of agents who attach a private value to receiving the good. The principal, instead of using monetary transfers (i.e. charging the ...
    • Robust auction design under multiple priors by linear and integer programming 

      Koçyiğit, Ç.; Bayrak, H. İ.; Pınar, M. Ç. (Springer New York LLC, 2018)
      It is commonly assumed in the optimal auction design literature that valuations of buyers are independently drawn from a unique distribution. In this paper we study auctions under ambiguity, that is, in an environment where ...
    • Robust bilateral trade with discrete types 

      Kargar, K.; Bayrak, H. I.; Pinar, M. Ç. (Springer Verlag, 2018)
      Bilateral trade problem is the most common market interaction in which a seller and a buyer bargain over an indivisible object, and the valuation of each agent about the object is private information. We investigate the ...
    • Robust screening under ambiguity 

      Pınar, M. Ç.; Kızılkale, C. (Springer, 2017)
      We consider the problem of screening where a seller puts up for sale an indivisible good, and a buyer with a valuation unknown to the seller wishes to acquire the good. We assume that the buyer valuations are represented ...
    • Worst-case large deviations upper bounds for i.i.d. sequences under ambiguity 

      Pınar, M. Ç. (Scientific and Technical Research Council of Turkey - TUBITAK,Turkiye Bilimsel ve Teknik Arastirma Kurumu, 2018-01-22)
      An introductory study of large deviations upper bounds from a worst-case perspective under parameter uncertainty (referred to as ambiguity) of the underlying distributions is given. Borrowing ideas from robust optimization, ...
