MemEIC: A Step Toward Continual and Compositional Knowledge Editing
Unlocking Continual & Compositional AI: MemEIC's Breakthrough
The dynamic nature of information necessitates continuously updating large vision-language models (LVLMs). While recent knowledge editing techniques hint at promising directions, they often focus on editing a single modality (vision or language) in isolation. This prevalent practice neglects the inherent multimodality of LVLMs and the continuous nature of knowledge updates, potentially leading to suboptimal editing outcomes when considering the interplay between modalities and the need for ongoing knowledge refinement. To address these limitations, we propose MemEIC, a novel method for Continual and Compositional Knowledge Editing (CCKE) in LVLMs.

Introducing the CCKE Benchmark
We introduce Continual and Compositional Knowledge Editing (CCKE), the first benchmark for multimodal knowledge editing. CCKE assesses models under continual knowledge editing and compositional queries that require combining information from both visual and textual edits. We also propose Compositional Reliability (CompRel) to quantify how reliably a model integrates multiple updated knowledge pieces.
MemEIC: A Hybrid Editing Framework
MemEIC integrates external retrieval memory with internal model editing. It employs query decomposition, a modality-aware external memory (MEM-E) with separate storage units, and an internal separated knowledge integration (MEM-I) using dual LoRA adapters for visual and textual knowledge. A key innovation is the brain-inspired knowledge connector, selectively fusing information across modalities.
Demonstrated Superior Performance
Extensive experiments on the new CCKEB benchmark show MemEIC significantly improves performance on complex multimodal questions. It effectively preserves prior edits and achieves interference-free knowledge updates, setting a new benchmark for CCKE in LVLMs. MemEIC consistently outperforms prior methods in edit success and compositional reasoning tasks, demonstrating strong robustness against catastrophic forgetting.

MemEIC's Resilience: Handling Imperfect External Knowledge
In real-world scenarios, external retrieval can be noisy or incomplete. MemEIC is specifically designed to navigate these challenges, ensuring consistent performance.
MemEIC demonstrates remarkable robustness even when external memory retrieval is imperfect or noisy. By training with adversarial retrieval scenarios (e.g., 50% or 70% accuracy), the Knowledge Connector learns to cross-check external evidence against its internal memory.
This mechanism allows MemEIC to fall back on internal edits when external retrieval is unreliable, while still leveraging accurate external information. This prevents over-reliance on incorrect external knowledge and ensures reliable output, even in challenging real-world deployment conditions.
