MUSE: A Comprehensive AI Framework for Evaluating Machine Unlearning in Language Models

Practical Solutions for AI Language Models

Challenges in Language Models

Language models (LMs) face challenges related to privacy and copyright concerns due to their training on vast amounts of text data. This has led to legal and ethical issues, including copyright lawsuits and GDPR compliance.

Machine Unlearning Techniques

Data owners increasingly demand the removal of their data from trained models. This has prompted research into methods that can transform existing trained models to behave as if they had never been exposed to certain data, while maintaining overall performance and efficiency.

Addressing Challenges

Researchers have developed approximate unlearning methods, such as parameter optimization techniques and in-context unlearning, to provide practical alternatives. These methods aim to remove verbatim memorization, knowledge memorization, and privacy leakage while preserving utility, scalability, and sustained performance across multiple unlearning requests.

MUSE Evaluation Framework

The MUSE framework evaluates machine unlearning algorithms based on six key criteria: no verbatim memorization, no knowledge memorization, no privacy leakage, utility preservation, scalability, and sustainability. This comprehensive evaluation assesses the effectiveness of unlearning techniques in real-world scenarios, using datasets focused on unlearning Harry Potter books and news articles.

Research Findings

The evaluation of eight unlearning methods revealed significant challenges, including struggles with privacy leakage, model utility degradation, scalability issues, and sustainability problems. These findings underscore the limitations of existing approaches and emphasize the urgent need for more robust and balanced machine unlearning techniques.
