Bayesian Active Learning in the Presence of Nuisance Parameters

no code implementations23 Oct 2023 Sabina J. Sloman, Ayush Bharti, Julien Martinelli, Samuel Kaski

However, the introduction of nuisance parameters can lead to bias in the Bayesian learner's estimate of the target parameters, a phenomenon we refer to as negative interference.

Learning relevant contextual variables within Bayesian Optimization

no code implementations23 May 2023 Julien Martinelli, Ayush Bharti, Armi Tiihonen, S. T. John, Louis Filstroff, Sabina J. Sloman, Patrick Rinke, Samuel Kaski

Contextual Bayesian Optimization (CBO) efficiently optimizes black-box functions with respect to design variables, while simultaneously integrating contextual information regarding the environment, such as experimental conditions.

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.

Reactmine: a statistical search algorithm for inferring chemical reactions from time series data

no code implementations7 Sep 2022 Julien Martinelli, Jeremy Grignard, Sylvain Soliman, Annabelle Ballesta, François Fages

We present a CRN inference algorithmwhich enforces sparsity by inferring reactions in a sequential fashion within a search tree of boundeddepth, ranking the inferred reaction candidates according to the variance of their kinetics on theirsupporting transitions, and re-optimizing the kinetic parameters of the CRN candidates on the wholetrace in a final pass.
