Title: Smoothing techniques in nonsmooth optimisation and applications
Abstract: In this talk, we consider an application of smoothing techniques to a broad class of nonsmooth optimisation problems. This class includes functions represented as a difference of two, in general nonsmooth, convex functions and also functions represented as a difference of two Clarke regular functions. However, we assume that component functions in these representations are either maximum functions or smooth composition of discrete maximum functions. Numerical results with nonsmooth optimisation test problems are presented and different smoothing techniques are compared using these results. Finally, we demonstrate the application of smoothing techniques for solving some problems in data mining.

Title: Nonsmooth DC Optimisation: Methods and Applications

Date and time: Friday, 31 March 2017, 3:00–4:00pm
Location: Building 8 Level 9 Room 66 (AGR) RMIT City campus

Abstract: An unconstrained optimisation problem with the objective function represented as a difference of two convex functions is considered. Bundle methods for solving such problems are designed and their convergence is discussed. Applications of these methods in machine learning and regression analysis are also considered.

Bio: Adil Bagirov is an Associate Professor of Optimisation at Faculty of Science and Technology, Federation University Australia. He obtained his MSc degree in Applied Mathematics in 1983 from Baku State University, Azerbaijan and PhD degree in Mathematics in 2002 from the University of Ballarat. His research is focused on nonsmooth optimisation, nonconvex optimisation and applications.
