Practical Membership Inference Attacks against Fine-tuned Large Language Models via Self-prompt Calibration

no code implementations10 Nov 2023 Wenjie Fu, Huandong Wang, Chen Gao, Guanghua Liu, Yong Li, Tao Jiang

Prior attempts have quantified the privacy risks of language models (LMs) via MIAs, but there is still no consensus on whether existing MIA algorithms can cause remarkable privacy leakage on practical Large Language Models (LLMs).

An Event Correlation Filtering Method for Fake News Detection

no code implementations10 Dec 2020 Hao Li, Huan Wang, Guanghua Liu

To improve the detection performance of fake news, we take advantage of the event correlations of news and propose an event correlation filtering method (ECFM) for fake news detection, mainly consisting of the news characterizer, the pseudo label annotator, the event credibility updater, and the news entropy selector.
