Beyond Scale: the Diversity Coefficient as a Data Quality Metric for Natural Language Datasets

This repository provides the official implementation of the Task2Vec Diversity Coefficient for computing natural language data diversity from the following paper:

Beyond Scale: the Diversity Coefficient as a Data Quality Metric Demonstrates LLMs are Pre-trained on Formally Diverse Data. Alycia Lee, Brando Miranda, Sanmi Koyejo. Paper: https://arxiv.org/abs/2306.13840

This repository also contains code for generating GINC datasets and computing the Diversity Coefficient of those datasets (see ginc/).

Getting Started

diversity/ contains the Task2Vec diversity coefficient computation for natural language data. See Quick-start ) for a tutorial of computing the diversity coefficient for a language dataset.** Run diversity/runner.sh to compute Task2Vec embeddings and diversity coefficient for c4, WikiText-103, and The Pile.

When cloning your main repository in the future, you will need to initialize the submodules as well by using:

cd ~
git clone --recurse-submodules https://github.com/<user>/beyond-scale-language-data-diversity.git

If you forget to use --recurse-submodules, you can still initialize the:

git clone https://github.com/<user>/beyond-scale-language-data-diversity.git
cd ~/beyond-scale-language-data-diversity
git submodule update --init --recursive

Note: to push the changes to submodule cd there and do git cmds there. In the main repo folder to do git pushes/edits to the main repo code.

For all experiments including the ginc data set: ginc/ contains Generative In-Context learning Dataset from the original GINC repo.

Run ginc/runner_generate.sh to generate GINC datasets with varying number of HMMs and number of symbols. Run ginc/runner_train.sh to train GPT-2 Transformers on GINC datasets using wandb.

Conda Install

Create conda env:

conda create -n beyond_scale_div_coeff python=3.11 -y
# conda activatexport HOME=/data/
conda activate beyond_scale_div_coeff
pip install -e ~/beyond-scale-language-data-diversity
# conda remove --name beyond_scale_diiv_coeff --all

Venv Install

Create venv python environment:

deactivate
# mkdir ~/.virtualenvs
ls ~/.virtualenvs
python3.11 -m venv ~/.virtualenvs/beyond_scale_div_coeff
source ~/.virtualenvs/beyond_scale_div_coeff/bin/activate
pip install --upgrade pip
which python
pip install -e ~/beyond-scale-language-data-diversity
