This data set is created by randomly sampling 1M documents from [the large supervised proportional mixture](https://github.com/google-research/text-to-text-transfer-transformer/blob/733428af1c961e09ea0b7292ad9ac9e0e001f8a5/t5/data/mixtures.py#L193) from the [T5](https://github.com/google-research/text-to-text-transfer-transformer) repository.

The code to produce this sampled dataset can be found [here](https://github.com/chenyu-jiang/text-to-text-transfer-transformer/blob/main/prepare_dataset.py).
