07.03.22 – Professor Lénaïc Chizat, a mathematician at EPFL, has won the 2022 Activity Group on Imaging Science Best Paper Prize from the Society for Industrial and Applied Mathematics (SIAM).

The Society for Industrial and Applied Mathematics (SIAM) is a nonprofit international community with more than 14,000 individual members comprising almost 500 academic, manufacturing, research and development, service and consulting organizations, government, and military organizations worldwide are institutional members.

Every two years, SIAM awards the SIAM Activity Group on Imaging Science Best Paper Prize “to the author(s) of the most outstanding paper on mathematical and computational aspects of imaging published within the four calendar years preceding the year prior to the award year.” Candidates include papers on image formation, inverse problems in imaging, image processing, image analysis, image interpretation and understanding, computer graphics, and visualization.

This year, the SIAM selection committee has awarded the Prize to Professor Lénaïc Chizat, who holds the Chair of Dynamics of Learning Algorithms at EPFL’s School of Basic Sciences (Institute of Mathematics). The selection committee cites Chizat’s paper “Sparse optimization on measures with over-parameterized gradient descent”, published in May 2021 in the journal Mathematical Programming. The SIAM citation states that Chizat’s paper is awarded: “for laying out the mathematical foundations of particles-based methods for off-the-grid sparse regularization.”

The Prize will be during the upcoming virtual SIAM Conference on Imaging Science (IS22), (21-25 March 2022). As the winner, Chizat will be presenting the paper as a plenary lecture.
