Academic Seminar |Large-Scale Ranking and Selection delivered by Prof. Jeff HONG
Title: Large-Scale Ranking and Selection
Speaker: Prof. Jeff HONG, City University of Hong Kong
Time: 14:30 – 15:30, Tuesday, August 21, 2018
Venue: Boardroom, Dao Yuan Building
Ranking and selection (R&S) aims to design statistical procedures that can select the one with the highest mean performance from a group of alternatives. It is a classical problem in the areas of statistics and stochastic simulation. In recent years, more and more researchers are looking at R&S problems with a large number of alternatives (often in the orders of thousands to even millions) and solving them in parallel computing environment. In this talk, we will first talk about how to design efficient fully-sequential procedures in parallel computing environment, and then introduce a completely new idea/procedure that achieves the lower bound of the increasing order of the sample size for R&S problems.
