STAR Group

Safe & Trustworthy AI Resarch (STAR) group, led by Fei Sun, studies AI safety and trustworthiness. We are part of the State Key Laboratory of AI Safety.

At STAR Group, we believe interpretability is a key to building safe and trustworthy AI. Our research focuses on the knowledge mechanisms of AI models—how they learn, memorize, recall, update/edit, and forget knowledge. We also explore the security and privacy impacts of deploying AI in real-world applications, with a special focus on LLMs and recommender systems.
