Welcome to Deita (Data-Efficient Instruction Tuning for Alignment) Project!

We will continue to update, please stay tuned!

What is Deita?

Deita is an open-sourced project designed to facilitate Automatic Data Selection for instruction tuning in Large Language Models (LLMs).

It includes:

• Open-sourced Toolkits for automatic data selection in instruction tuning
• Deita Datasets: A series of extremely lightweight, high-quality alignment SFT data. We release 6k-sized and 10k-sized datasets in the first release
• Deita Models: A series of powerful models on par with SOTA chat LLMs with an extremely efficient instruction tuning Process. Deita models can be obained by training with 10x less instruction tuning data compared with other SOTA LLMs

News

• :fire: [03/2024] Our datasets have been used by Huggingface to creat the Zephyr Gemma Model.
• 📄 [01/2024] Deita paper What Makes Good Data for Alignment? A Comprehensive Study of Automatic Data Selection in Instruction Tuning has been accepted by ICLR2024!
• :fire: [01/2024] Deita pipelines have been released! With one line code and configurations, a high-quality data subset for alignment can be selected.
• 📚 [01/2024] Our scorer datasets deita-complexity-scorer-data and deita-quality-scorer-data have been released.
• :fire: [12/2023] We release the first collection of the Deita resources here, which include a series of extremely lightweight, effective sft datasets, the data complexity/quality scorer models, as well as the resulted deita chat models.

Performance

:bell: Still curious about how far a small amount of high-quality data can lead LLMs?

Deita may provide an answer for you:

DEITA models are based on Mistral-7B-v0.1. :fire:

Please refer to this table for full evaluations including Open LLM Leaderboard as well, which includes DEITA models with LLaMA base models and comparisons with other data selection approaches.

:running_man: How to start?

Installation

  git clone https://github.com/hkust-nlp/deita.git
  cd deita
  pip install -e .

Data Sample Scoring

If you wish to assess the quality of a response for a single sample, you can follow these steps:

from deita.selection.scorer import Llama_Scorer

model_name_or_path = "hkust-nlp/deita-quality-scorer"

scorer = Llama_Scorer(model_name_or_path)

# example input
input_text = "word to describe UI with helpful tooltips" # Example Input
output_text = "User-friendly or intuitive UI" # Example Output
quality_score = scorer.infer_quality(input_text, output_text)

print(quality_score)
# 2.0230105920381902

Deita also supports VLLM for faster inference. If you want to use VLLM for inference,

pip install vllm

And set is_vllm = True when initilizing scorer

scorer = Llama_Scorer(model_name_or_path, is_vllm = True)

To assess other dimensions of data samples, please refer to the examples/scoring

Deita Pipelines

You can use deita pipelines to perform a variety of operations on the dataset with only one line code and configurations.

• Dataset Scoring

from deita.pipeline import Pipeline

pipeline = Pipeline("score_pipeline", 
                    data_path = args.data_path,   # json file with sharegpt format
                    scorer = args.scorer,   # [mistral, llama]
                    scorer_name_or_path = args.scorer_name_or_path,  # scorer name or path e.g. hkust-nlp/deita-complexity-scorer
                    is_vllm = args.is_vllm,  # launch with vllm [True, False]
                    score_type = args.score_type, # [complexity, quality]
                    output_path = args.output_path)  # output path (json format)

pipeline.run()

• Get Embeddings

We use Huggingface Accelerate to enhance efficiency:

from deita.pipeline import Pipeline

embed_pipeline = Pipeline("embed_pipeline", 
                          data_path = args.data_path,   # json file with sharegpt format
                          output_path = args.output_path,  # output path (pickle format)
                          model_name_or_path = args.model_name_or_path,  # model name or path e.g. mistralai/Mistral-7B-v0.1
                          max_length = args.max_length,
                          use_flash_attention = args.use_flash_attention,  
                          batch_size_per_device = args.batch_size_per_device,
                          conv_template = args.conv_template,
                          only_answer = args.only_answer,
                          random_shuffle = args.random_shuffle,
                          bfloat16 = True
                          )

• Score-first, Diversity-aware Selection

from deita.pipeline import Pipeline

filter_pipeline = Pipeline("filter_pipeline", 
                          data_path = args.data_path,  # json file with sharegpt format
                          other_data_path = args.other_data_path,  # embedding file path (pickle format)
                          threshold = args.threshold,  # filter threshold default: 0.9 
                          data_size = args.data_size,  # size of selected data
                          chunk_size = args.chunk_size,  # used for more efficient GPU computing  default: 100000
                          sort_key = args.sort_key,  # default: "complexity_scores,quality_scores"
                          output_path = args.output_path,  # json format output path
                          distance_metric = args.distance_metric,  # default: cosine
                          embedding_field = args.embedding_field,  # default: embedding
                          is_compression = args.is_compression,  # default: False
                          device = args.device  # GPU IDX, default: 0
                          )

filter_pipeline.run()
