Title: LAROS: a convex optimization approach for feature extractionSpeaker: Dr. Xuan Vinh Doan Affiliation: Warwick Business School - University of WarwickLocation: Room 572A Huxley BuildingTime: 3:00pmAbstract. We propose a convex optimization formulation using nuclear norm and $ell_1$-norm to find a large approximately rank-one submatrix (LAROS) for a given matrix. We are able to characterize the...

Title: Large Scale Numerical Shape Optimisation Speaker: Dr. Stephan Schmidt Affiliation: Location: CPSE Seminar room (C615 Roderic Hill)Time: 4:30pmAbstract. Shape Optimisation problems are a special sub-class of optimisation problems with PDE constraints, where the domain in which the PDE is defined becomes the unknown to be found. The Hadamard Theorem states that given sufficient regularity,... Read more »

Title: Coordinating Flexible Responsive Electricity Demand via Smart Grids Speaker: Dr. Daniel Livengood Affiliation: Location: CPSE Seminar room (C615 Roderic Hill)Time: 2:00pmAbstract. As the electric grid evolves into a 'smart' grid, there is renewed interest in developing and implementing strategies for integrating flexible, responsive electric demand into the perpetual task of balancing electricity supply and...

Title: Scenario-Free Stochastic Programming with Polynomial Decision RulesSpeaker: Dimitra BampouAffiliation: Department of Computing - Imperial College LondonLocation: CPSE Seminar room (C615 Roderic Hill)Time: 5:00pmAbstract. Multi-stage stochastic programming provides a versatile framework for optimal decision making under uncertainty, but it gives rise to hard functional optimization problems since the adaptive recourse decisions must be modeled as...
