TOFU: Task of Fictitious Unlearning 🍢

The TOFU dataset serves as a benchmark for evaluating unlearning performance of large language models on realistic tasks. The dataset comprises question-answer pairs based on autobiographies of 200 different authors that do not exist and are completely fictitiously generated by the GPT-4 model. The goal of the task is to unlearn a fine-tuned model on various fractions of the forget set.

Applicability 🚀

The dataset is in QA format, making it ideal for use with popular chat models such as Llama2, Mistral, or Qwen. However, it also works for any other large language model. The corresponding code base is written for the Llama2 chat, and Phi-1.5 models, but can be easily adapted to other models.

Loading the Dataset

To load the dataset, use the following code:

from datasets import load_dataset
dataset = load_dataset("locuslab/TOFU", "full")

Available forget sets are:

• forget01: Forgetting 1% of the original dataset, all entries correspond to a single author.
• forget05: Forgetting 5% of the original dataset, all entries correspond to a single author.
• forget10: Forgetting 10% of the original dataset, all entries correspond to a single author.

Retain sets corresponding to each forget set are also available, which can be used to train an Oracle model.

Codebase

The code for training the models and the availability of all fine-tuned models can be found at our GitHub repository.
