HPOBench: A Collection of Reproducible Multi-Fidelity Benchmark Problems for HPO
The authors propose HPOBench, which includes 7 existing and 5 new benchmark families, with a total of more than 100 multi-fidelity benchmark problems.

Gaussian Process Optimization in the Bandit Setting: No Regret and Experimental Design
The authors resolve the important open problem of deriving regret bounds for this setting, which imply novel convergence rates for GP optimization.

Multi-Fidelity Bayesian Optimization with Unreliable Information Sources
The authors propose rMFBO (robust MFBO), a methodology to make any GP-based MFBO scheme robust to the addition of unreliable information sources. rMFBO comes with a theoretical guarantee that its performance can be bound to its vanilla BO analog.

A Study of Bayesian Neural Network Surrogates for Bayesian Optimization
In this paper, the authors study BNNs as alternatives to standard GP surrogates for optimization. We consider a variety of approximate inference procedures for finite-width BNNs, including

On the role of Model Uncertainties in Bayesian Optimization
In this work, the authors provide an extensive study of the relationship between the BO performance (regret) and uncertainty calibration for popular surrogate models and compare them across both synthetic and real-world experiments.

Causal Bayesian Optimization
This paper studies the problem of globally optimizing a variable of interest that is part of a causal model in which a sequence of interventions can be performed. This problem arises in biology, operational research, communications.
