# Description

This dataset is a sampled subset of the [Pile](https://huggingface.co/datasets/EleutherAI/pile) dataset. 
We used [DSIR](https://github.com/p-lambda/dsir) a data selection tool with importance resampling for subsampling.

The subset sample distribution is:

```json
{
   'Pile-CC': 19767,
   'OpenWebText2': 12424,
   'FreeLaw': 3752,
   'USPTO Backgrounds': 1055,
   'Wikipedia (en)': 813,
   'PubMed Central': 576,
   'PubMed Abstracts': 499,
   'BookCorpus2': 285,
   'Books3': 266,
   'Gutenberg (PG-19)': 228,
   'StackExchange': 184,
   'PhilPapers': 112,
   'YoutubeSubtitles': 91,
   'OpenSubtitles': 75,
   'ArXiv': 56,
   'NIH ExPorter': 47,
   'Enron Emails': 39,
   'HackerNews': 29,
   'Github': 28,
   'EuroParl': 12
}
```


The dataset contains ~100M words of text. This can be checked with:

```python
from datasets import load_dataset

ds = load_dataset("PatrickHaller/dsir-pile-10M-words")

count = 0
for row in ds["train"]:
    count += len(row["text"].split(" "))

print(count)

# Out: 9999894
```
