DCLM-baseline

DCLM-baseline is a 4T token / 3B document pretraining dataset that achieves strong performance on language model benchmarks.

Below are comparisions of model trained on DCLM-baseline with other models in the 7B regime.

Uses

Direct Use

DCLM-Baseline is intended to be used as a research baseline for the DCLM benchmark. It demonstrates the importance of data curation in training performant language models.

Out-of-Scope Use

DCLM-Baseline is not intended for training production-ready models or for specific domains such as code and math. It may not perform as well as domain-specific datasets for these tasks. Due to these limitations, the dataset is intended for research use only. DCLM-Baseline is a subset of the DCLM-Pool, which is a corpus of 240 trillion tokens derived from Common Crawl. The dataset is in plain text format.

Dataset Creation

Curation Rationale

DCLM-Baseline was created to demonstrate the effectiveness of the DCLM testbed in developing high-quality training sets for language models. It serves as a proof of concept for the data curation strategies enabled by DCLM and is designed to be a research baseline for the benchmark.

Source Data

Data Collection and Processing

DCLM-Baseline was created by applying a series of cleaning, filtering, and deduplication steps to the raw Common Crawl data (DCLM-Pool). The key steps include:

Heuristic cleaning and filtering (reproduction of RefinedWeb)
Deduplication using a Bloom filter
Model-based filtering using a fastText classifier trained on instruction-formatted data (OpenHermes 2.5 and r/ExplainLikeImFive)

Who are the source data producers?

The source data is from Common Crawl, which is a repository of web crawl data.

Personal and Sensitive Information

[More Information Needed]

Bias, Risks, and Limitations

The dataset may contain biases present in the Common Crawl data. The dataset's performance on code and math tasks is limited compared to its performance on language understanding tasks. DCLM-Baseline is designed for research purposes only.

Recommendations

Users should be aware of the potential biases and limitations of the dataset, especially when using it for specific domains like code and math. The dataset should only be used for research purposes in the context of the DCLM benchmark.
