Machine Learning in R (mlr)

OpenML is readily integrated with mlr through the mlr3oml package.

library(mlr3oml)
library(mlr3)

# Search for specific datasets
odatasets = list_oml_data(
number_features = c(10, 20),
number_instances = c(45000, 50000),
number_classes = 2
)

# Get dataset
odata = odt(id = 1590)
# Access the actual data
odata$data

# Convert to an mlr3::Task
tsk_adult = as_task(odata, target = "class")

Key features:

  • Query and download OpenML datasets and use them however you like
  • Build any mlr learner, run it on any task and save the experiment as run objects
  • Upload your runs for collaboration or publishing
  • Query, download and reuse all shared runs

There is also an older (deprecated) OpenML R package.
