Efficient computation of the Knowledge Gradient for Bayesian Optimization

no code implementations30 Sep 2022 Juan Ungredda, Michael Pearce, Juergen Branke

Bayesian optimization is a powerful collection of methods for optimizing stochastic expensive black box functions.

One Step Preference Elicitation in Multi-Objective Bayesian Optimization

no code implementations27 May 2021 Juan Ungredda, Mariapia Marchi, Teresa Montrone, Juergen Branke

We address this issue by using a multi-objective Bayesian optimization algorithm and allowing the DM to select a preferred solution from a predicted continuous Pareto front just once before the end of the algorithm rather than selecting a solution after the end.

Bayesian Optimisation for Constrained Problems

no code implementations27 May 2021 Juan Ungredda, Juergen Branke

Many real-world optimisation problems such as hyperparameter tuning in machine learning or simulation-based optimisation can be formulated as expensive-to-evaluate black-box functions.

Bayesian Optimisation vs. Input Uncertainty Reduction

no code implementations31 May 2020 Juan Ungredda, Michael Pearce, Juergen Branke

Particularly when performing simulation optimisation to find an optimal solution, the uncertainty in the inputs significantly affects the quality of the found solution.
