Title: High-precision solutions for linear programs over the rational numbersSpeaker: Ambros GleixnerAffiliation: Zuse Institute BerlinLocation: CPSE seminar room (C615 Roderic Hill)Time: 3:00pmAbstract. About the speaker.

Title: Bayesian Optimization for Learning Robot ControlSpeaker: Dr. Marc DeisenrothAffiliation: Department of Computing - Imperial College LondonLocation: Room 217 Huxley BuildingTime: 3:00pmAbstract. Statistical machine learning has been a promising direction in control and robotics for more than a decade since data-driven learning allows us to reduce the amount of engineering knowledge that is otherwise required....

Title: Visual-Inertial Odometry (VIO) Using Nonlinear OptimizationSpeaker: Dr. Stefan LeuteneggerAffiliation: Dyson Robotics Lab - Imperial College LondonLocation: Room 217 Huxley BuildingTime: 2:00pmAbstract. Visual-inertial fusion for state estimation and mapping has recently drawn increased attention. The sensing modalities offer compelling complementary characteristics, since inertial measurements provide strong short-term temporal correlations, while visual correspondences in images form...

Title: Static and Dynamic Assortment OptimizationSpeaker: Prof. Kalyan TalluriAffiliation: Imperial College London Business SchoolLocation: LT 311 Huxley BuildingTime: 2:00pmAbstract. Assortment Optimization is the problem of offering an optimal assortment from a ground set. Customers choose one of the offered products or decide not to purchase any. The dynamic version of this problem with finite inventories... Read more »

Title: Markov Random Field Optimization in Medical Image AnalysisSpeaker: Dr. Ben GlockerAffiliation: Department of Computing - Imperial College LondonLocation: Room 140 HuxleyTime: 2:00pmAbstract. Markov Random Fields (MRFs) are widely used for modelling image analysis problems, such as segmentation, denoising, and motion estimation. In this presentation, I will provide a brief overview of different applications of... Read more »

Title: Worst-case complexity of nonlinear optimization: Where do we stand?Speaker: Prof. Philippe TointAffiliation: Department of Mathematics – Université de NamurLocation: CPSE seminar room (C615 Roderic Hill)Time: 11:00amAbstract. We review the available results on the evaluation complexity of algorithms using Lipschitz-continuous Hessians for the approximate solution of nonlinear and potentially nonconvex optimization problems. Here, evaluation complexity... Read more »

Title: Formal Proofs for Nonlinear OptimizationSpeaker: Dr. Victor MagronAffiliation: Department of Electrical and Electronic Engineering - Imperial College LondonLocation: Room 217 Huxley BuildingTime: 2:00pmAbstract. We present a formally verified global optimization framework. Given a semialgebraic or transcendental function f and a compact semialgebraic domain K, we use the nonlinear maxplus template approximation algorithm to provide... Read more »
