Solving Inverse Problems at the Advanced Photon Source by Machine Learning and Optimization
Speaker: Sven Leyffer, Deputy Division Director / Senior Computational Mathematician, Mathematics and Computer Science Division, Argonne National Laboratory
Date: July 3, 2024
Coffee and Social: 10:30 AM – 11:00 AM
Time: 11:00 AM – 12:00 PM
Location: Hybrid, Bldg. 240, Conference Room 4301-T
Host: Srutarshi Banerjee
Location: See Meeting URL on the cels-seminars website which will require an Argonne login.
Description: I will review some recent approaches to solving inverse problems arising at the Advanced Photon Source (APS). These approaches combine traditional optimization techniques for inverse problems with machine-learning (ML) techniques for faster reconstruction. I will also discuss a challenging problem arising in the design scanning trajectories that can be formulated as an optimal design-of-experiment problem.
Bio: Sven Leyffer joined the Mathematics and Computer Science Division at Argonne in 2002, where he is now a senior computational mathematician. Sven is a SIAM Fellow, and a senior fellow of the University of Chicago/Argonne Computation Institute. He is the current SIAM President and serves on the editorial boards of Computational Optimization and Applications, and Mathematics of Computation. In 2006, Leyffer (along with two colleagues) received the Lagrange Prize in Continuous Optimization, which is awarded only once every 3 years. In 2016, he received the Farkas Prize from the INFORMS Optimization Society. Leyffer obtained his Ph.D. in 1994 from the University of Dundee, Scotland, and held postdoctoral research positions at Dundee, Argonne, and Northwestern University.
