mlr3batchmark

r-cmd-check CRAN status StackOverflow Mattermost

A connector between mlr3 and batchtools. This allows to run large-scale benchmark experiments on scheduled high-performance computing clusters.

The package comes with two core functions for switching between mlr3 and batchtools to perform a benchmark:

Example

library("mlr3")
library("batchtools")
library("mlr3batchmark")
tasks = tsks(c("iris", "sonar"))
learners = lrns(c("classif.featureless", "classif.rpart"))
resamplings = rsmp("cv", folds = 3)

design = benchmark_grid(
  tasks = tasks,
  learners = learners,
  resamplings = resamplings
)

reg = makeExperimentRegistry(NA)
## No readable configuration file found

## Created registry in '/tmp/Rtmp8DlMZQ/registry704553adf7a88' using cluster functions 'Interactive'
ids = batchmark(design, reg = reg)
## Adding algorithm 'run_learner'
