Accelerating Look-ahead in Bayesian Optimization: Multilevel Monte Carlo is All you Need

1 code implementation3 Feb 2024 Shangda Yang, Vitaly Zankin, Maximilian Balandat, Stefan Scherer, Kevin Carlberg, Neil Walton, Kody J. H. Law

We leverage multilevel Monte Carlo (MLMC) to improve the performance of multi-step look-ahead Bayesian optimization (BO) methods that involve nested expectations and maximizations.
