Scalarisation-based risk concepts for robust multi-objective optimisation

1 code implementation16 May 2024 Ben Tu, Nikolas Kantas, Robert M. Lee, Behrang Shafei

Robustification refers to the strategy that is used to marginalise over the uncertainty in the problem.

Random Pareto front surfaces

1 code implementation2 May 2024 Ben Tu, Nikolas Kantas, Robert M. Lee, Behrang Shafei

As a motivating example, we investigate how these statistics can be used within a design of experiments setting, where the goal is to both infer and use the Pareto front surface distribution in order to make effective decisions.

Multi-objective optimisation via the R2 utilities

1 code implementation19 May 2023 Ben Tu, Nikolas Kantas, Robert M. Lee, Behrang Shafei

As part of our work, we show that these utilities are monotone and submodular set functions which can be optimised effectively using greedy optimisation algorithms.

Joint Entropy Search for Multi-objective Bayesian Optimization

1 code implementation6 Oct 2022 Ben Tu, Axel Gandy, Nikolas Kantas, Behrang Shafei

Many real-world problems can be phrased as a multi-objective optimization problem, where the goal is to identify the best set of compromises between the competing objectives.
