## Dataset Creation

The AG-Pair dataset is built from the original dataset AG's News that contains 120k training samples from four topics.
Given a pair of news as input, the model has to predict whether they are belonging to the same topic (Same) or not (Different).

To generate this dataset, samples in AG are iterated in random order and have an equal chance to combine a sample in the same topic or the other three topics.
Thus the numbers of training samples in two classes are both 60k.
Moreover, each news in AG's News occurs exactly twice in the AG-Pair dataset to keep the same word frequency.
