DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OWOS/45/">Wa
 sserstein Distance to Independence Models</a>\nby Bernd Sturmfels (MPI Lei
 pzig) as part of One World Optimization seminar\n\n\nAbstract\nAn independ
 ence model for discrete random variables is a variety in a probability sim
 plex. \nGiven any data distribution\, we seek to minimize the Wasserstein 
 distance to the model.\nThat distance comes from a polyhedral norm whose u
 nit ball is dual to an alcoved polytope.\nThe solution to our optimization
  problem is a piecewise algebraic function of the data.\nIn this talk we d
 iscuss the algebraic and geometric structure of this function.\n\nReferenc
 e: arXiv:2003.06725\n\nThe address and password of the zoom room of the se
 minar are sent by e-mail on the mailinglist of the seminar one day before 
 each talk\n
