Lrnr_randomForest: Random Forests

In jeremyrcoyle/sl3: Pipelines for Machine Learning and Super Learning

Description

This learner provides fitting procedures for random forest models, using the randomForest package, using randomForest function.

Format

R6Class object.

Value

Learner object with methods for training and prediction. See Lrnr_base for documentation on learners.

Parameters

ntree = 500

Number of trees to grow. This should not be set to too small a number, to ensure that every input row gets predicted at least a few times.

keep.forest = TRUE

If TRUE, forest is stored, which is required for prediction.

nodesize = 5

Minimum number of observations in terminal nodes.

...

Other parameters passed to randomForest.
