  1. Dec. 5, 2019CompMath & CO Joint Seminar - Andreas Griewank

    Title: How can we optimize nonsmooth objectives globally?

    Speaker: Andreas Griewank
    Affiliation: Humboldt University, Germany
    Room: MC 5501

    Abstract:

    In machine learning objective functions that are only piecewise smooth and should be globally minimized abound. The standard method of dealing with them is to apply a stochastic gradient method disregarding the rare points of nonsmoothness and hoping for the best as far as global optimality of the computed solution is concerned.

  2. Dec. 5, 2019Algebraic Combinatorics Seminar - Krystal Guo

    Title: Inverses of Trees

    Speaker: Krystal Guo
    Affiliation: Centre de Recherches Mathématiques & Université de Montréal
    Room: MC 5417

    Abstract:

    A tree is invertible if and only if it has a perfect matching.

    Godsil considers an invertible tree T and finds that the inverse of the adjacency matrix has entries in {0, ±1} and is the signed adjacency matrix of a graph which contains T.

  3. Dec. 6, 2019Tutte Colloquium - Koray Karabina

    Title: Biometric security: Design, implementation, and challenges

    Speaker: Koray Karabina
    Affiliation: Florida Atlantic University
    Room: MC 5501

    Abstract:

    Biometric based cybersecurity technologies offer significant advantages in authentication, identification, and access control mechanisms.
