This research explores how machine unlearning can selectively remove specific knowledge from trained large language models while maintaining overall performance.

• Demonstrates that not all data points require equal unlearning treatment
• Focuses particularly on removing named entities for privacy protection
• Addresses critical security concerns around personal data persistence in AI
• Proposes more nuanced approaches to the unlearning problem

This research is significant for security professionals as it provides insights for more effective privacy protection in AI systems, particularly when handling sensitive personal information that needs to be selectively removed.

Not All Data Are Unlearned Equally
