| Title: | Collection of Machine Learning Data Sets for 'mlr3' |
|---|---|
| Description: | A small collection of interesting and educational machine learning data sets which are used as examples in the 'mlr3' book (<https://mlr3book.mlr-org.com>), the use case gallery (<https://mlr3gallery.mlr-org.com>), or in other examples. All data sets are properly preprocessed and ready to be analyzed by most machine learning algorithms. Data sets are automatically added to the dictionary of tasks if 'mlr3' is loaded. |

Classification data to predict handwritten digits. Obtained using the mlr3oml package.
Binarized version of the original data set. The multi-class target column has been converted to
a two-class nominal target column by re-labeling the majority class as positive ("P") and all
others as negative ("N"). Originally converted by Quan Sun.
Contains 64 features and 5620 observations.
Target column is "binaryclass".
All feature variables "input1", ..., "input64" (number of on pixels in each block) have
been coerced to integers.
The target variable has been renamed from "binaryClass" to "binaryclass".

Classification data to predict the species of penguins from the palmerpenguins package. A better alternative to the iris data set.
The unit of measurement have been removed from the column names. Lengths are given in millimeters (mm), weight in gram (g).
Observations with missing values have been removed.
Factor variables are one-hot encoded.

Observations of the test set have a missing value in the target column "survived".
Column '"survived"' has been re-encoded to a factor with levels '"yes"' and '"no"'.
Id column has been removed.
Passenger class "pclass" has been converted to an ordered factor.
Features "sex" and "embarked" have been converted to factors.
