Title: Generating structured music with local search and machine learningSpeaker: Dr. Dorien HerremansAffiliation: School of Electronic Engineering and Computer Science - Queen Mary UniversityLocation: LT 144 Huxley BuildingTime: 3:30pmAbstract. Many state of the art music generation/improvisation systems generate music that sounds good on a note-to-note level. However, these compositions often lack long term structure or... Read more »

Title: Families of Convex and Non-Convex Composite Optimization Problems for Signal Processing and Computer VisionSpeaker: Dr. Stefanos ZafeiriouAffiliation: Department of Computing - Imperial College LondonLocation: Room 217 - 218 Huxley BuildingTime: 3:00pmAbstract. About the speaker. Stefanos Zafeiriou is a Senior Lecturer (equivalent to Associate Professor) in Pattern Recognition/Statistical Machine Learning for Computer Vision in the... Read more »

Title: Rescaled coordinate descent methods for Linear ProgrammingSpeaker: Dr. Giacomo ZambelliAffiliation: Department of Management - London School of Economics and Political ScienceLocation: SALC 10 Sherfield Building Time: 4:00pmAbstract. Simple coordinate descent methods such as von Neumann’s algorithm or Perceptron, both developed in the 50s, can be used to solve linear programming feasibility problems. Their convergence...

Title: Ambiguous Joint Chance Constraints under Mean and Dispersion InformationSpeaker: Prof. Daniel KuhnAffiliation: Risk Analytics and Optimization - Ecole Polytechnique Federale De Lausanne (EPFL)Location: Room 217 Huxley BuildingTime: 4:00pmAbstract. We study joint chance constraints where the distribution of the uncertain parameters is only known to belong to an ambiguity set characterized by the mean and... Read more »

Title: The Decision Rule Approach to Optimization Under Uncertainty: Theory and ApplicationsSpeaker: Dr. Angelos GeorghiouAffiliation: Automatic Control Laboratory - Swiss Federal Institute of Technology (ETH)Location: Room 217 Huxley BuildingTime: 3:00pmAbstract. Decision making under uncertainty has a long and distinguished history in operations research. However, most of the existing solution techniques suffer from the curse of... Read more »

Title: Revenue-Optimising Scheduling in Parallel Stochastic NetworksSpeaker: Dr. Giuliano CasaleAffiliation: Department of Computing - Imperial College LondonLocation: Room 145 Huxley BuildingTime: 4:00pmAbstract. Cloud applications are often deployed on multiple virtual machines (VMs) with heterogeneous compute capacities. In this setting, we consider the optimal static scheduling of users to application servers hosted in a set of... Read more »

Title: On the standard pooling problem and strong valid inequalitiesSpeaker: Dr. Claudia D AmbrosioAffiliation: Laboratory for Information - Ecole PolytechniqueLocation: Room 311 Huxley BuildingTime: 4:00pmAbstract. The focus of this talk will be on the standard pooling problem, i.e., a continuous, non-convex optimization problem arising in the chemical engineering context. First, we will introduce the problem... Read more »

Title: Large-scale MILP and MINLP problems in power system planningSpeaker: Dr. Ioannis KonstantelosAffiliation: Department of Electrical and Electronic Engineering - Imperial College LondonLocation: Room 218 Huxley BuildingTime: 4:00pmAbstract. Achieving the ambitious decarbonization goals set by governments worldwide will entail significant changes to the way electrical energy is generated, transmitted and used. The cost-effective integration of... Read more »

Title: On Optimal selection of fixed-size populations: an application to tree breedingSpeaker: Dr. Pietro BelottiAffiliation: FICO companyLocation: CPSE seminar room (C615 Roderic Hill)Time: 4:00pmAbstract. One of the problems that tree breeders face is the selection of a pedigree of trees with two aims: 1) conserving genetic diversity; 2) maximize response to selection. We tackled the... Read more »

Title: On some tractable optimization models dealing with uncertaintySpeaker: Prof. Patrick JailletAffiliation: Laboratory for Information and Decision Systems - MITLocation: LG19 seminar room Business SchoolTime: 12:00pmAbstract. In the first part of the talk we consider the minmax regret model for combinatorial optimization problems under uncertainty, which can be viewed as a zero-sum game played between... Read more »
