Cooperative Bayesian Optimization for Imperfect Agents

no code implementations7 Mar 2024 Ali Khoshvishkaie, Petrus Mikkola, Pierre-Alexandre Murena, Samuel Kaski

We introduce a cooperative Bayesian optimization problem for optimizing black-box functions of two variables where two agents choose together at which points to query the function but have only control over one variable each.

Multi-Fidelity Bayesian Optimization with Unreliable Information Sources

1 code implementation25 Oct 2022 Petrus Mikkola, Julien Martinelli, Louis Filstroff, Samuel Kaski

Over the past decade, many algorithms have been proposed to integrate cheaper, lower-fidelity approximations of the objective function into the optimization process, with the goal of converging towards the global optimum at a reduced cost.

Bayesian Optimization Augmented with Actively Elicited Expert Knowledge

no code implementations18 Aug 2022 Daolang Huang, Louis Filstroff, Petrus Mikkola, Runkai Zheng, Samuel Kaski

We design a multi-task learning architecture for this task, with the goal of jointly eliciting the expert knowledge and minimizing the objective function.

Targeted Active Learning for Bayesian Decision-Making

no code implementations8 Jun 2021 Louis Filstroff, Iiris Sundin, Petrus Mikkola, Aleksei Tiulpin, Juuso Kylmäoja, Samuel Kaski

Active learning is usually applied to acquire labels of informative data points in supervised learning, to maximize accuracy in a sample-efficient way.

Projective Preferential Bayesian Optimization

2 code implementations ICML 2020 Petrus Mikkola, Milica Todorović, Jari Järvi, Patrick Rinke, Samuel Kaski

This is demonstrated in a user experiment in which the user feedback comes in the form of optimal position and orientation of a molecule adsorbing to a surface.
