论文教你如何让AI知识编辑更精准
该论文提出一种路由专用双适配器编辑器（Route-Specialized Dual Adapters），通过相关性路由器决定是否对提示应用编辑记忆，并训练编辑适配器和局部性适配器分别处理编辑和未编辑的提示。在CF、ZSRE和MQUAKE三个基准（各包含1000个案例）上，使用LLaMA-3.1-8B-Instruct模型时分别达到0.8180、0.8946和0.9922的概率偏好准确率，在Qwen3-8B上也表现一致。消融实验表明，性能提升主要来自分离编辑注入与非路由抑制的机制，而非单纯增加LoRA容量。
When to Write and When to Suppress: Route-Specialized Dual Adapters for Memory-Assisted Knowledge Editing
Knowledge editing systems must update selected facts while preserving nearby but irrelevant behavior. This paper studies this problem in a memory-assisted setting where an edit memory is retrieved at inference time and a parameter-efficient adapter corrects the model's object preference. We argue that the central design question is not only how to write an edit, but also when to suppress it. We introduce \method{}, a route-specialized dual-adapter editor. A relevance router first decides whether a prompt should receive an edit memory. Routed prompts use an edit adapter trained to prefer the new object over the original object; unrouted non-direct prompts use a separate locality adapter trained to preserve or restore the original-object preference. We evaluate \method{} on three 1,000-case protocols, \cf{}, \zsre{}, and \mquake{}, under the same memory protocol and two 7B/8B base models. On Llama-3.1-8B-Instruct, \method{} obtains the best overall probability-preference accuracy on all three benchmarks: 0.8180 on \cf{}, 0.8946 on \zsre{}, and 0.9922 on \mquake{}. The same trend holds on Qwen3-8B. Router ablations show that the relevant memory boundary differs across datasets: a lexical neural router is safest on \cf{}, while BGE embedding routing is better on \zsre{} and \mquake{}. Component and module ablations show that the gain mainly comes from separating edit injection from off-route suppression rather than from simply increasing LoRA capacity.
