Outsourced Bayesian Optimization

no code implementations ICML 2020 Dmitrii Kharkovskii, Zhongxiang Dai, Bryan Kian Hsiang Low

This paper presents the outsourced-Gaussian process-upper confidence bound (O-GP-UCB) algorithm, which is the first algorithm for privacy-preserving Bayesian optimization (BO) in the outsourced setting with a provable performance guarantee.

Nonmyopic Gaussian Process Optimization with Macro-Actions

no code implementations22 Feb 2020 Dmitrii Kharkovskii, Chun Kai Ling, Kian Hsiang Low

This paper presents a multi-staged approach to nonmyopic adaptive Gaussian process optimization (GPO) for Bayesian optimization (BO) of unknown, highly complex objective functions that, in contrast to existing nonmyopic adaptive BO algorithms, exploits the notion of macro-actions for scaling up to a further lookahead to match up to a larger available budget.
