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".
Pre-processing
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".
