Models Trained with Human Selection

This is a collection of the language models trained using Human selection, each with approximately 1B parameters, trained on different random mixtures of data. This project aims to validate the generalization capabilities of the RegMix approach (https://huggingface.co/papers/2407.01492) from small-scale (e.g., 1M parameters) to large-scale (e.g., 1B parameters) models.

Key Features

• Model Size: 5 separate models trained with different seeds, each with ~1B parameters
• Training Data: Human selection (from The Pile paper) data mixtures on the RegMix-Data dataset
• Purpose: The Human selection is a strong baseline for our method RegMix

Dataset

The models were trained using the RegMix-Data dataset, which is split into different domains from The Pile dataset.

Training Hyperparameters

How to Load a Model

You can load any model using the corresponding branch with the Hugging Face Transformers library:

from transformers import AutoModel, AutoTokenizer

model = AutoModel.from_pretrained("sail/data-mixture-human-1b", revision="seed-1")
tokenizer = AutoTokenizer.from_pretrained("sail/data-mixture-human-1b", revision="seed-1")

Data Mixture

The specific data mixture used for training this 1B model is as follows, which can be also found in our code:

  valid_the_pile_pile_cc: 1.0

Domain weights will be normalized to make sure their sum is 1.0 for train sets in our code.

Model Variants

To access different model variants, simply change the revision parameter in the from_pretrained method to the desired seed (e.g., "seed-2", "seed-3"), and the maxium seed is 5.

Model Performance

We evaluated each model using lm-evaluation-harness. The performance metric for each task is the average of 0-shot to 5-shot accnorm (accuracy normalized, if available) or acc (accuracy) scores.

Usage Notes

• These models are primarily intended for research purposes.
• Performance may vary depending on the specific task and domain.
