In our paper, we demonstrate superior optimization performance on tiny budgets for a variety of tasks, including single- and multi-objective, high-dimensional inputs, discrete inputs noisy outcomes, including parallel/async and early termination settings. proceedings.mlr.press/v293/o…

Did you know that concrete accounts for 8% of global CO2 emissions? I'm delighted to share that after 2 years of development, we've successfully deployed our strong, low-carbon emission "AI concrete mix" at the latest Meta datacenter. engineering.fb.com/2025/07/1…

This work was a collaboration between the Meta Adaptive Experimentation and Infrastructure Data Science teams, UIUC, and Amrize. This mix was designed using batch multi-objective Bayesian optimization with BoTorch. Source code and data is available at github.com/facebookresearch/…

Is there a bug in OpenReview for #UAI2024? We submitted 3 papers, and none of the reviewers updated their responses and there are only reject or accept decisions—no meta-review.

Software package announcement! The Geometric Kernels package, which implements various geometric Gaussian process models from my papers - on manifolds, graphs, and similar - is now on PyPi! It can be installed with `pip install geometric_kernels`. Check it out!
Excited to announce a new release of GeometricKernels! You can now install the package via `pip install geometric_kernels`! Featuring new spaces, efficient GP sampling, and a much simpler interface, in addition to brand new tutorials & enhanced docs!

EI its variants are the most popular acquisition functions in BayesOpt, but is no longer SoTA. We show that this is bc EI is hard to optimize numerically due to vanishing gradients, study consequences of this & propose a drop in replacement. Follow below for a sick BoTorch demo!
