Overview

We explore the pretraining data detection problem: given a piece of text and black-box access to an LLM without knowing the pretraining data, can we determine if the model was trained on the provided text? To faciliate the study, we built a dynamic benchmark WikiMIA to systematically evaluate detecting methods and proposed Min-K% Prob 🕵️, a method for detecting undisclosed pretraining data from large language models.

📘 WikiMIA Datasets

The WikiMIA datasets serve as a benchmark designed to evaluate membership inference attack (MIA) methods, specifically in detecting pretraining data from extensive large language models. Access our WikiMIA datasets directly on Hugging Face.

Loading the Datasets:

from datasets import load_dataset
LENGTH = 64
dataset = load_dataset("swj0419/WikiMIA", split=f"WikiMIA_length{LENGTH}")

• Available Text Lengths: 32, 64, 128, 256.
• Label 0: Refers to the unseen data during pretraining. Label 1: Refers to the seen data.
• WikiMIA is applicable to all models released between 2017 to 2023 such as LLaMA1/2, GPT-Neo, OPT, Pythia, text-davinci-001, text-davinci-002 ...

📘 BookMIA Datasets for evaluating MIA on OpenAI models

The BookMIA datasets serve as a benchmark designed to evaluate membership inference attack (MIA) methods, specifically in detecting pretraining data from OpenAI models that are released before 2023 (such as text-davinci-003). Access our BookMIA datasets directly on Hugging Face.

The dataset contains non-member and member data:

• non-member data consists of text excerpts from books first published in 2023
• member data includes text excerpts from older books, as categorized by Chang et al. in 2023.

Loading the Datasets:

from datasets import load_dataset
dataset = load_dataset("swj0419/BookMIA")

• Available Text Lengths: 512.
• Label 0: Refers to the unseen data during pretraining. Label 1: Refers to the seen data.
• WikiMIA is applicable to OpenAI models that are released before 2023 text-davinci-003, text-davinci-002 ...

🚀 Run our Min-K% Prob & Other Baselines

Our codebase supports many models: Whether you're using OpenAI models that offer logits or models from Huggingface, we've got you covered:

• OpenAI Models:

  • text-davinci-003
  • text-davinci-002
  • ...

• Huggingface Models:

  • meta-llama/Llama-2-70b
  • huggyllama/llama-70b
  • EleutherAI/gpt-neox-20b
  • ...

🔐 Important: When using OpenAI models, ensure to add your API key at Line 38 in run.py:

openai.api_key = "YOUR_API_KEY"

Use the following command to run the model:

python src/run.py --target_model text-davinci-003 --ref_model huggyllama/llama-7b --data swj0419/WikiMIA --length 64

🔍 Parameters Explained:

• Target Model: Set using --target_model. For instance, --target_model huggyllama/llama-70b.

• Reference Model: Defined using --ref_model. Example: --ref_model huggyllama/llama-7b.

• Data Length: Define the length for the WikiMIA benchmark with --length. Available options: 32, 54, 128, 256.

📌 Note: For optimal results, use fixed-length inputs with our Min-K% Prob method (When you evalaute Min-K% Prob method on your own dataset, make sure the input length of each example is the same.)

📊 Baselines: Our script comes with the following baselines: PPL, Calibration Method, PPL/zlib_compression, PPL/lowercase_ppl
