New Bayesian Optimization Algorithm Uses Product-of-Experts GP Models

Researchers have introduced BO-pro-c, a novel Bayesian optimization algorithm that utilizes a product-of-experts Gaussian process (GP) model. This approach addresses the computational limitations of traditional GP models, which struggle with large datasets due to their cubic complexity. By combining multiple local GP experts, GP-pro-c offers improved uncertainty quantification and reduced computational costs while preserving global correlations. Experiments show that BO-pro-c achieves competitive optimization performance, with a 0.9% reduction in simple regret and a 39.4% decrease in computational overhead compared to standard GP-based Bayesian optimization.

    Bayesian Optimisation Using Product-of-Experts Gaussian Process Models with Uncertainty Calibration

    arXiv:2609.15555v1 Announce Type: new Abstract: Bayesian optimisation (BO) typically relies on a single global Gaussian process (GP) model as its surrogate model. However, GP regression has cubic computational complexity in the number of training data points, limiting its applica…
