Title: Chebyshev approximation problems and Remez method applicability.
Date and Time: Friday, August 2nd, 3.00pm – 4.00pm
Location: Building 8 Level 9 Room 66 (AGR) RMIT City campus
|Abstract: In this presentation, I am going to talk about three types of Chebyshev approximation problem: approximation by univariate polynomials, multivariate polynomials and rational functions. The objective function in the first two problems are convex and the corresponding optimisation problems can be solved by applying a general convex approximation method, while the third type is a quasi-convex and needs a specially developed method to solve it. In this talk, I will demonstrate the transformation of the problem and highlight surprising similarities passing from one formulation to another.
Bio: Dr. Sukhorukova is holding two PhD degrees: one from the University of Ballarat (currently, Federation University Australia), completed in 2004 and another one is from Saint-Petersburg State University (Russia) completed in 2006. Dr. Nadia Sukhorukova is working in the area of Mathematical Optimisation and its application to data analysis, data mining, signal processing, location-allocation problems and other real-life applications. Dr. Sukhorukova is also working on a number of mathematical problems appearing in the area of Chebyshev (uniform) approximation (ARC Discovery grant DP180100602).
