    Title: Basis Shape Loci and the Positive Grassmannian

    Speaker: Cameron Marcot
    Affiliation: University of Waterloo
    Room: MC 6483

    Abstract: We study the set of k-dimensional planes in R^n admitting a basis of vectors with prescribed supports.

  2. Oct. 17, 2018Continuous Optimization Seminar - Steve Vavasis

    Title: Tutorial on back-propagation and automatic differentiation

    Speaker: Steve Vavasis
    Affiliation: University of Waterloo
    Room: MC 5479

    Abstract: In this presentation, I'll cover the basics of automatic differentiation (AD).

  3. Oct. 18, 2018Algebraic Graph Theory Seminar- Chris Godsil

    Title: Graphs of Homomorphisms

    Speaker: Chris Godsil
    Affiliation: University of Waterloo
    Room: MC 6486

    Abstract: If X and Y are graphs and f is a function on V (X) taking values in V (Y ), then the graph of
    f is the subset formed by the pairs (x; f(x)) for x in V (X).
