B3O: Scalable Boltzmann Batch Bayesian Optimization

arXiv:2606.30228v1 Announce Type: new Abstract: Modern engineering workflows increasingly rely on massive parallel simulation, driving the need for scalable, large-batch Bayesian Optimization (BO). Existing batch BO methods, however, incur large computational cost or rely on approximations that erode batch diversity. We propose B3O (Boltzmann Batch Bayesian Optimization), a framework that reframes batch generation as a pure sampling problem: drawing samples directly from the Boltzmann distribution defined by the acquisition function avoids the bottlenecks of existing large-batch methods. Theor

Why this matters
Why now

This development addresses a critical bottleneck in large-scale AI research and engineering, enabling faster and more efficient development of complex models and systems.

What changes

The computational cost and limitations of existing large-batch Bayesian Optimization methods are potentially mitigated by a new approach based on Boltzmann distribution sampling.
