September 2017

Sung Ha Kang, Georgia Tech, Variational image processing and computational challenges

September 26 | 3:00 pm - 4:00 pm EDT

Starting with an introduction to variational/PDE based image processing, this talk will focus on new developments of fast algorithms for higher order variational imaging models.  For example, recent developments of fast algorithms, based on operator splitting, augmented Lagrangian, and alternating…

Murthy Gudatti, NC State

October 3 | 3:00 pm - 4:00 pm EDT

Sercan Yildiz, SAMSI,Polynomial Optimization with Sums-of-Squares Interpolants

October 10 | 3:00 pm - 4:00 pm EDT

Sums-of-squares certificates define a hierarchy of relaxations for polynomial optimization problems which are parametrized with the degree of the polynomials in the sums-of-squares representation. Each level of the hierarchy generates a lower bound on the true optimal value, which can…
