Webb20 sep. 2024 · To support users in determining well-performing hyperparameter configurations for their algorithms, datasets and applications at hand, SMAC3 offers a robust and flexible framework for Bayesian Optimization, which can improve performance within a few evaluations. Webb21 mars 2016 · Performance of machine learning algorithms depends critically on identifying a good set of hyperparameters. While recent approaches use Bayesian optimization to adaptively select configurations, we focus on speeding up random search through adaptive resource allocation and early-stopping.

Webb25 nov. 2024 · Bayesian optimization [11, 12] is an efficient approach to find a global optimizer of expensive black-box functions, i.e. the functions that are non-convex, expensive to evaluate, and do not have a closed-form to compute derivative information.For example, tuning hyper-parameters of a machine learning (ML) model can …
WebbIt is worth noting that Bayesian optimization techniques can be effective in practice even if the underlying function f being optimized is stochastic, non-convex, or even non-continuous. 3.

Webb$\begingroup$ Not well enough educated on the topic to make this a definitive answer, but I would think Bayesian Optimization should suffer the same fate as most efficient optimizers with highly multi-modal problems (see: 95% of machine learning problems): it zeros in on the closest local minimum without "surveying" the global space. I think …
