Prof. Jean-Philippe Vert is a researcher interested in machine learning and computational biology, working as:
- Senior researcher at Google Brain in Paris
- Research professor at the Centre for Computational Biology at Mines ParisTech.
Sorting and ranking an array are fundamental routines in machine learning, used to compute rank-based statistics, cumulative distribution functions (CDFs), quantiles, or to select closest neighbors and labels. The sorting and ranking functions are however piecewise constant (the sorting permutation of a vector does not change if the entries of that vector are infinitesimally perturbed) and therefore have no gradient information to back-propagate. In this talk, I will discuss different approaches to design differentiable sorting and ranking operators, using regularization or perturbation techniques, and highlight some applications in learning to rank or matrix factorization.
The Center for Intelligent Systems at EPFL (CIS) is a collaboration among IC, SB, and STI that brings together researchers working on different aspects of Intelligent Systems. In June 2020, CIS has launched its CIS Colloquia featuring invited notable speakers.
