  1. Nov. 17, 2017Tutte Colloquium - Simon Lacoste-Julien

    Title: Recent Advances in Frank-Wolfe Optimization

    Speaker: Simon Lacoste-Julien
    Affiliation: University of Montreal
    Room: MC 5501

    Abstract:

    The Frank-Wolfe (FW) optimization algorithm has lately re-gained popularity thanks in particular to its ability to nicely handle the structured constraints appearing in machine learning and signal processing applications. However, its convergence rate is known to be slow (sublinear) when the solution lies at the boundary.

  2. Nov. 22, 2017Continuous Optimization Seminar - Henry Wolkowicz

    Title: Alternating Direction Method of Multipliers for the SDP Relaxation of the Quadratic Assignment Problem

    Speaker: Henry Wolkowicz
    Affiliation: University of waterloo
    Room: MC 5479

    Abstract:

    The semidefinite programming (SDP) relaxation has proven to be extremely strong for many hard discrete optimization problems. This is in particular true for the quadratic assignment problem (QAP), arguably one of the hardest NP-hard discrete optimization problems.

  3. Nov. 22, 2017Joint PureMath/C&O Semimar - Mehdi Karimi

    Title: Sum-of-Squares Proofs in Optimization

    Speaker: Mehdi Karimi
    Affiliation: University of Waterloo
    Room: MC 5501

    Abstract:

    The old concept of sum-of-squares found its way into optimization and even machine learning. I will talk about this quickly evolving research area known as convex algebraic geometry.
