default_rf

This is a helper function that constructs a default random forest mlr3::LearnerRegr which is for example used in
default_surrogate.
Constructs a ranger learner &#8220;"regr.ranger"&#8221; with <code>num.trees = 100</code>, <code>keep.inbag = TRUE</code> and
<code>se.method = "jack"</code>.

A modern and flexible approach to Bayesian Optimization / Model
Based Optimization building on the 'bbotk' package. 'mlr3mbo' is a toolbox
providing both ready-to-use optimization algorithms as well as their fundamental
building blocks allowing for straightforward implementation of custom
algorithms. Single- and multi-objective optimization is supported as well as
mixed continuous, categorical and conditional search spaces. Moreover, using
'mlr3mbo' for hyperparameter optimization of machine learning models within the
'mlr3' ecosystem is straightforward via 'mlr3tuning'. Examples of ready-to-use
optimization algorithms include Efficient Global Optimization by Jones et al.
