Constrained Bayesian Optimisation with Multiple Information Sources

arXiv:2607.00865v1 Announce Type: new Abstract: Bayesian Optimisation (BO) under unknown constraints is particularly challenging when feasible regions are small. In such settings, existing methods that typically rely solely on evaluations of the true objective and constraints struggle to efficiently explore the design space. However, many real-world applications offer auxiliary data sources (e.g. surrogate models or simplified simulations) that can support early exploration. Despite this potential, their integration into constrained BO remains largely unexplored. We propose a general multi-sou

Why this matters
Why now

The increasing complexity of AI model training and design necessitates more efficient optimisation techniques, particularly in resource-constrained environments.

Why it’s important

This research addresses a critical limitation in Bayesian Optimisation by leveraging multiple information sources, potentially accelerating AI development and broader scientific discovery where data is scarce or expensive.

What changes

The ability to integrate auxiliary data sources into constrained Bayesian Optimisation expands the applicability of these methods to real-world problems with limited direct observation access.
