DESCRIPTION:Prof. Jean-Philippe Vert\nProf. Jean-Philippe Vert is a resear
 cher interested in machine learning and computational biology\, working as
 :\n\n	Senior researcher at Google Brain in Paris\n	Research professor at t
 he Centre for Computational Biology at Mines ParisTech.\n\nAbstract:\nSort
 ing and ranking an array are fundamental routines in machine learning\, us
 ed to compute rank-based statistics\, cumulative distribution functions (C
 DFs)\, quantiles\, or to select closest neighbors and labels. The sorting 
 and ranking functions are however piecewise constant (the sorting permutat
 ion of a vector does not change if the entries of that vector are infinite
 simally perturbed) and therefore have no gradient information to back-prop
 agate. In this talk\, I will discuss different approaches to design differ
 entiable sorting and ranking operators\, using regularization or perturbat
 ion techniques\, and highlight some applications in learning to rank or ma
 trix factorization.\n\n\nThe Center for Intelligent Systems at EPFL (CIS) 
 is a collaboration among IC\, SB\, and STI that brings together researcher
 s working on different aspects of Intelligent Systems. In June 2020\, CIS 
 has launched its CIS Colloquia featuring invited notable speakers.\n
