Real-World Data

The datasets below were obtained from the UCI Machine Learning Repository or StatLog. They were transformed to a standard format, attributes followed by outputs, and incomplete examples were removed. Sometimes a dataset contains both training and test examples; they are combined in one file, training examples followed by test examples. Note that attributes are not scaled. Users should scale the attributes after the dataset has been split into training and test parts, if they do so.

Binary Datasets
