Small helper function that can save some typing when creating mutiple learner objects. Calls makeLearner multiple times internally.

makeLearners(cls, ids = NULL, type = NULL, ...)

Arguments

cls

(character)
Classes of learners.

ids

(character)
Id strings. Must be unique. Default is cls.

type

(character(1))
Shortcut to prepend type string to cls so one can set cls = "rpart". Default is NULL, i.e., this is not used.

...

(any)
Optional named (hyper)parameters. If you want to set specific hyperparameters for a learner during model creation, these should go here. You can get a list of available hyperparameters using getParamSet(<learner>). Alternatively hyperparameters can be given using the par.vals argument but ... should be preferred!

Value

(named list of Learner). Named by ids.
