New method infers entity-level training data in LLMs

Researchers have introduced a new method for entity-level membership inference in large language models (LLMs). This approach aims to determine if information about a specific real-world entity, rather than just individual data samples, was included in an LLM's training data. The proposed strategies involve using limited entity clues to construct prompts, elicit responses, and then infer membership based on semantic features within the generated text. Experiments demonstrated that these methods can achieve high accuracy, significantly outperforming adapted baseline approaches. AI

IMPACT This research could lead to better privacy auditing for LLMs, helping to identify if sensitive entity-level information is being memorized during training.

    Have You Ever Seen Them? Entity-level Membership Inference through Interrogating Large Language Models

    Large Language Models (LLMs) raise growing concerns about privacy leakage and copyright compliance. Membership inference is a key tool for assessing such risks, but existing studies mainly focus on whether specific samples or sample-based data units are used for training. We argu…
