I am working with the "Digit1" dataset introduced by the book "Semi-Supervised Learning" by chapalle et. al, as one of the benchmark datasets in the field.

In the dataset description located at: http://olivier.chapelle.cc/ssl-book/benchmarks.pdf comes:

The class label was set according to the tilt angle, with the boundary corresponding to an upright digit.

Somewhere else in the document comes that there are only 2 classes in this dataset. From these two explanations I still can not understand how exactly the labels are defined. I would be thankful If someone could help me with this.

It seems this set contains only rotated "1"s (plus some noise and rescales), and the decision is whether the digit is rotated right or left from the upright position.
