Relaxed joint chance constraints with surrogate tail bounds
ESD Research Seminar by Arjun Ramachandra – Many applications in power systems, supply chains, and transportation involve uncertain outcomes and optimisation decisions over multiple time periods while requiring high reliability. Joint chance constraints (JCC) enforce strict reliability but are overly conservative, while single chance constraints (SCC) offer flexibility at the cost of performance.
Learning-augmented optimisation for transportation, supply chain, and service systems
ESD Research Seminar by Huang Yiduo – This talk introduces Postdoctoral Research Associate Huang Yiduo’s research programme at the intersection of optimisation, stochastic modelling, and data-driven methods for complex service and supply chain systems.
Stochastic dynamics in curbside operations: Pricing, facility design, and access control
ESD Research Seminar by Liu Xinyu, Cindy – This talk presents rigorous, practical frameworks using continuous-time Markov decision processes (MDPs) and game-theoretic queues.
A behavioural model for exploration vs exploitation: Theoretical framework and experimental evidence
ESD Research Seminar by Yifan Feng – How do people navigate the exploration-exploitation (EE) trade-off when making repeated choices with unknown rewards? We study this question through the lens of multi-armed bandit problems and introduce a novel behavioural model, Quantal Choice with Adaptive Reduction of Exploration (QCARE).
What can quantum AI learn from biological intelligence?
ESD Research Seminar by Thiparat Chotibut – Designing scalable quantum machine learning (QML) models with potential quantum advantage on Noisy Intermediate-Scale Quantum (NISQ) devices remains a major challenge.
A brief history of weak dependencies
ESD Research Seminar by Paul Doukhan – More than a purely formal exposition, the aim is to demonstrate the advantages and disadvantages of each of the most commonly used concepts, depending on the intended purpose and the types of models involved.
From applications to structure and back
ESD Research Seminar by Antonio Frangioni – Professor Antonio Frangioni will summarise some of the main lines of his research in this seminar, emphasising how he is primarily driven by the desire of solving real-world, difficult optimisation problems.
Sum of squares submodularity
ESD Research Seminar by Georgina Hall – This talk will demonstrate the usefulness of t-sos submodularity through three applications: (i) a new convex approach to submodular regression, involving minimal manual tuning; (ii) a systematic procedure to derive lower bounds on the submodularity ratio in approximate submodular maximisation, and (iii) improved difference-of-submodular decompositions for difference-of-submodular optimisation.
Regression analysis of semiparametric Cox–Aalen transformation models with application to a randomised HIV/AIDS trial
ESD Research Seminar by Xi Ning – This talk will study a class of the semiparametric Cox-Aalen transformation models for regression analysis.
Zoning in emerging logistics systems: New theory and practice
ESD Research Seminar by Sheng Liu – New zoning methods and their applications to manage emerging logistics systems in retail and last-mile delivery will be discussed in this talk.
