MetaKE: Meta-learning Aligned Knowledge Editing via Bi-level Optimization
🤖AI Summary
Researchers propose MetaKE, a new framework for knowledge editing in Large Language Models that addresses the 'Semantic-Execution Disconnect' through bi-level optimization. The method treats edit targets as learnable parameters and uses a Structural Gradient Proxy to align edits with the model's feasible manifold, showing significant improvements over existing approaches.
Key Takeaways
- →Current knowledge editing methods suffer from misalignment between semantic targets and model execution capabilities.
- →MetaKE reframes knowledge editing as a bi-level optimization problem with learnable edit targets.
- →The framework introduces a Structural Gradient Proxy to handle complex solver differentiation.
- →Theoretical analysis shows MetaKE automatically aligns edit directions with model feasible regions.
- →Experimental results demonstrate significant outperformance compared to existing baseline methods.
