Did you know?
Bayesian Optimization [Moc74, JSW98] (BO) is a sequential optimization strategy originally proposed to solve the single-objective black-box optimiza-tion problem that is costly to evaluate. Here, we shall restrict our discussion to the single-objective case. BO typically starts with sampling an initial design of … See more For real-valued search variables, the simplest usage is via the fminfunction: And you could also have much finer control over most … See more This implementation differs from alternative packages/libraries in the following features: 1. Parallelization, also known as batch-sequential optimization, for which several different approaches are implemented here. 2. … See more The following infill-criteria are implemented in the library: 1.
