The original Statlog (Landsat Satellite) dataset from UCI machine learning repository is a multi-class classification dataset. Here, the training and test data are combined. The smallest three classes, i.e. 2, 4, 5 are combined to form the outliers class, while all the other classes are combined to form an inlier class.
