In black-box optimization the goal is to solve the problem min {x∈Ω} (), where is a computationally expensive black-box function and the domain Ω is commonly a hyper-rectangle. Due to the fact that evaluations are computationally expensive, the goal is to reduce the number of evaluations of to a few hundred. In the …
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.
