A simple mlr3misc::Dictionary storing objects of class TuningSpace.
Each tuning space has an associated help page, see mlr_tuning_spaces_[id].
Format
R6::R6Class object inheriting from mlr3misc::Dictionary.
Methods
See mlr3misc::Dictionary.
S3 methods
as.data.table(dict, ..., objects = FALSE)
mlr3misc::Dictionary ->data.table::data.table()
Returns adata.table::data.table()with fields "key", "label", "learner", and "n_values" as columns. Ifobjectsis set toTRUE, the constructed objects are returned in the list column namedobject.
