OpenML (version 1.7)

runTaskMlr: Run mlr learner on OpenML task.

Description

Run task with a specified learner from mlr and produce predictions.

Usage

runTaskMlr(task, learner, measures = NULL, verbosity = NULL, seed = 1,
  scimark.vector = NULL, models = TRUE, ...)

Arguments

task

[OMLTask] An OpenML task.

learner

[Learner] Learner from package mlr to run the task.

measures

[Measure] Additional measures that should be computed.

verbosity

[integer(1)] Print verbose output on console? Possible values are: 0: normal output, 1: info output, 2: debug output. Default is set via setOMLConfig.

seed

[numeric(1)|OMLSeedParList ] Set a seed to make the run reproducible. Default is 1 and sets the seed using set.seed(1).

scimark.vector

[numeric(6)] Optional vector of performance measurements computed by the scientific SciMark benchmark. May be computed using the rscimark R package. Default is NULL, which means no performance measurements.

models

[logical(1)] This argument is passed to benchmark. Should all fitted models be stored in the ResampleResult? Default is TRUE.

...

[any] Further arguments that are passed to convertOMLTaskToMlr.

Value

[list] Named list with the following components:

run

The OMLRun object.

bmr

Benchmark result returned by benchmark.

flow

The generated OMLFlow object.

Examples

# NOT RUN {
  library(mlr)
  ## run a single flow (learner) on a single task
  task = getOMLTask(57)
  lrn = makeLearner("classif.rpart")
  res = runTaskMlr(task, lrn)
  ## the result "res" is a list, storing information on the actual "run", the
  ## corresponding benchmark result "bmr" and the applied "flow"
# }
