4 Autres (ouvrages, prix, etc.)

4.1 Jérôme Bolte et Edouard Pauwels recoivent le Prix Lagrange en Optimisation Continue

source : Franck Iutzeler

Dr. Jérôme Bolte and Dr. Edouard Pauwels, Toulouse School of Economics, are the 2024 recipients of the Lagrange Prize in Continuous Optimization. According to the award citation, the team received the prize for their paper “Conservative set valued fields, automatic differentiation, stochastic gradient methods and deep learning,” published in Mathematical Programming in 2020. “Bolte and Pauwels introduce generalized derivatives called conservative fields and provide variational formulas for non-smooth automatic differentiation oracles with applications in stochastic gradient methods.”

The pair model the algorithmic differentiation operation via new variational objects called conservative set valued fields. They also conduct the convergence analysis to critical points for non-smooth stochastic first-order methods. Their paper combines techniques from several fields including non-smooth analysis, first-order stochastic approximation, machine learning, and algorithmic differentiation, with a central role played by o-minimal geometry. Dr. Bolte and Dr. Pauwels thus provide a remarkable theoretical and algorithmic contribution to the field of continuous optimization.

The Lagrange Prize in Continuous Optimization is awarded every three years for an outstanding contribution in the area of continuous optimization published in the six calendar years prior to the award year. The Mathematical Optimization Society (MOS) administers the prize and it is awarded jointly by MOS and SIAM.
