Stack R Documentation
Learner Stacking
Description
A Stack is a special Learner that combines multiple other learners,
"stacking" their predictions in columns.
Format
R6Class object.
Value
Learner object with methods for training and prediction. See
Lrnr_base for documentation on learners.
Parameters
...Parameters should be individual Learners.
Common Parameters
Individual learners have their own sets of parameters. Below is a list of shared parameters, implemented by Lrnr_base, and shared
by all learners.
covariatesA character vector of covariates. The learner will use this to subset the covariates for any specified task
outcome_typeA variable_type object used to control the outcome_type used by the learner. Overrides the task outcome_type if specified
...All other parameters should be handled by the invidual learner classes. See the documentation for the learner class you're instantiating
