Special Seminar: Gauges, Sparsity, and BundlesSpecial Events
|Speaker:||Dr. Michael Friedlander, University of British Columbia|

Gauge functions significantly generalize the notion of a norm, and gauge optimization is the class of problems for finding the element of a convex set that is minimal with respect to a gauge. These conceptually simple problems appear in a remarkable array of applications. Their gauge structure allows for a special kind of duality framework that may lead to new algorithmic approaches. I will illustrate these ideas with applications in signal processing, including low-rank matrix recovery.
A Department Tea will follow the Talk in the Alder Room.
