mlr_resamplings_insample function

Insample Resampling

Uses all observations as training and as test set.

Dictionary

This Resampling can be instantiated via the dictionary mlr_resamplings or with the associated sugar function rsmp():

mlr_resamplings$get("insample")
rsmp("insample")

Examples

# Create a task with 10 observations
task = tsk("penguins")
task$filter(1:10)

# Instantiate Resampling
insample = rsmp("insample")
insample$instantiate(task)

# Train set equal to test set:
setequal(insample$train_set(1), insample$test_set(1))

# Internal storage:
insample$instance # just row ids
