DESCRIPTION:ISS Informal Systems Seminar\n\n\n	Speaker: Nicolas Gast – INRIA
 \, France \n\n\n \n\n\n	\n\n	Presentation on YouTube.\n\n	Abstract: Many reso
 urce allocation problems can be modeled as « weakly coupled MDPs ». In suc
 h a problem\, an operator is faced with a population of entities whose sta
 te evolves over time. The evolution of the entities are coupled only throu
 gh the actions of the controller. These problems are in general computatio
 nally hard for a finite population of entities but are interestingly easie
 r when the population is infinite. In particular\, there exists different 
 LP-based relaxations (including the famous Whittle index) that generally p
 rovide near-optimal solutions. The goal of this talk is to introduce these
  policies\, and to present recent results on when they become asymptotical
 ly optimal as the number of resources goes to infinity.\n\n	\n	Biography: Ni
 colas Gast is a tenured research scientist at Inria (Grenoble\,France) sin
 ce 2014\, and currently visiting MIT for the semester. He graduated from E
 cole Normale Superieure (Paris\,France) in 2007 and received a Ph.D. from 
 the University of Grenoble in 2010. He was a research fellow at EPFL from 
 2010 to 2014. His research focuses on the development and the use of stoch
 astic models and optimization methods for the design of control algorithms
  in large-scale systems.\n\n
