# RegMix Data
## Dataset Description
The RegMix Data is a curated dataset derived from the Pile-Uncopyrighted, specifically designed for the RegMix paper (https://huggingface.co/papers/2407.01492). This dataset aims to facilitate the automatic identification of high-performing data mixtures for language model pre-training by formulating it as a regression task.
### Key Features:
- Size: Approximately 1TB disk space, 250B tokens
- Distribution: Follows the natural token distribution of domain examples
- Organization: Examples from different domains are separated into individual files
## Dataset Structure
The dataset is organized into two main directories: `train` and `valid`, each containing domain-specific JSONL files. The file naming convention is as follows:
```
[domain]-[identifier]-[number].jsonl
```
For example: `arxiv-10-74305611.jsonl`
### Domains Included:
arxiv, gutenberg_pg_19, pubmed_central, dm_mathematics, hackernews, stackexchange, enron_emails, nih_exporter, ubuntu_irc, europarl, philpapers, uspto_backgrounds, freelaw, pile_cc, wikipedia_en, github, pubmed_abstracts
## Usage
We recommend downloading the entire dataset snapshot instead of using the traditional `load_dataset` function, as the RegMix code is integrated with the [TinyLlama framework](https://github.com/jzhang38/TinyLlama).
To download the dataset:
```python
from huggingface_hub import snapshot_download
LOCAL_DIR = "regmix-data"
snapshot_download(repo_id="sail/regmix-data",
repo_type='dataset',
local_dir=LOCAL_DIR,
local_dir_use_symlinks=False)
```
This will download the entire snapshot, containing 34 JSON line files (17 for train, and 17 for valid), to your specified local directory.
## Data Preprocessing
Our [code](https://github.com/sail-sg/regmix) will preprocess these domain files into binary format with domain prefixes. It allows for random sampling of the dataset using user-defined data mixtures (i.e., domain weights).
## Acknowledgements
We extend our gratitude to the creators of the [Pile-Uncopyrighted dataset](https://huggingface.co/datasets/monology/pile-uncopyrighted) for their efforts in removing copyrighted content from the original Pile dataset, making this work possible.
