default_acqfunction: Default Acquisition Function

In mlr3mbo: Flexible Bayesian Optimization

Default Acquisition Function

Description

Chooses a default acquisition function, i.e. the criterion used to propose future points. For synchronous single-objective optimization and a purely numeric parameter space, defaults to mlr_acqfunctions_cb with lambda = 3. For synchronous single-objective optimization and a mixed numeric-categorical parameter space, defaults to mlr_acqfunctions_cb with lambda = 1. For synchronous multi-objective optimization, defaults to mlr_acqfunctions_smsego. For asynchronous single-objective optimization, defaults to mlr_acqfunctions_stochastic_cb.

Usage

default_acqfunction(instance)

Arguments

instance

(bbotk::OptimInstance). An object that inherits from bbotk::OptimInstance.

Value
