SPACE: Source-free Proxy Anchor Concept Erasure for MLLMs
Researchers introduce SPACE, a source-free machine unlearning framework for multimodal large language models that removes sensitive data without access to original training data. The two-stage approach uses text-guided proxy anchors and dual-constraint semantic isolation to erase target concepts while maintaining model performance, addressing growing privacy and regulatory compliance needs.
