SPACE: Source-free Proxy Anchor Concept Erasure for MLLMs

In three linesSPACE is a source-free machine unlearning framework for MLLMs that erases sensitive concepts without access to original visual data. Two stages: Text-Guided Proxy Anchor Selection (TPAS) and Dual-Constraint Semantic Isolation (DCSI). Validated on 6 datasets with performance comparable to data-dependent methods.
