DESCRIPTION:Prof. Katie Bouman\, California Institute of Technology\, USA\
 nThis event is part of the EPFL Seminar Series in Imaging.\n\nAbstract. A
 s imaging requirements become more demanding\, we must rely on increasingl
 y sparse and/or noisy measurements that fail to paint a complete picture. 
 Computational imaging pipelines\, which replace optics with computation\, 
 have enabled image formation in situations that are impossible for convent
 ional optical imaging. For instance\, the first black hole image\, publish
 ed in 2019\, was only made possible through the development of computation
 al imaging pipelines that worked alongside an Earth-sized distributed tele
 scope. However\, remaining scientific questions motivate us to improve thi
 s computational telescope to see black hole phenomena still invisible to u
 s and to meaningfully interpret the collected data. This talk will discuss
  how we are leveraging and building upon recent advances in machine learni
 ng in order to achieve more efficient uncertainty quantification of recons
 tructed images as well as to develop techniques that allow us to extract t
 he evolving structure of our own Milky Way's black hole over the course of
  a night.\n\nBiography. Katherine L. (Katie) Bouman is a Rosenberg Scholar
  and an assistant professor in the Computing and Mathematical Sciences\, E
 lectrical Engineering\, and Astronomy Departments at the California Instit
 ute of Technology. Before joining Caltech\, she was a postdoctoral fellow 
 in the Harvard-Smithsonian Center for Astrophysics. She received her Ph.D.
  in the Computer Science and Artificial Intelligence Laboratory (CSAIL) at
  MIT in EECS\, and her bachelor's degree in Electrical Engineering from th
 e University of Michigan.
