  1. Jan. 17, 2018Special Seminar - Yi Zhou

    Title: Stochastic algorithms for distributed optimization and machine learning

    Speaker: Yi Zhou
    Affiliation: Georgia Institute of Technology
    Room: MC 5501


    In the big data era, machine learning acts as a powerful tool to transform data into knowledge that helps us make predictions and decisions. It has strong ties to the field of optimization, in the way the latter provides methods and theory.

  2. Jan. 18, 2018Algebraic Graph Theory Seminar - Chris Godsil

    Title: Quantum Latin Squares and Magic Unitaries

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


    A quantum Latin square is an n x n array of vectors such that vectors in any row or any column form an orthonormal basis for Cn. A magic unitary matrix is an n x n array of projections such that each row and column sums to I.

  3. Jan. 22, 2018Special Seminar - Jean-Francois Biasse

    Title: Are cryptosystems based on ideal lattices quantum-safe ?

    Speaker Jean-Francois Biasse
    Affiliation: University of South Florida
    Room:  QNC 1501


    Shor's algorithm factors RSA integers and solves the Discrete Logarithm Problem (DLP) in quantum polynomial time. Therefore, alternatives to these cryptosystems must be developed to replace the current cryptographic schemes. One of the most interesting family of schemes that have been proposed for the replacement of RSA-based and DLP-based primitives relies on the hardness of finding short vectors in Euclidean lattices.
