# 知识无关增强 (Knowledge-Agnostic Augmentation)
## 定义
知识无关增强是一种**规则驱动的机械式数据增强**,仅操作表面特征而不引入语义级新信息。
## 示例
- **文本**:将描述中的 "created" 替换为 "built"(同义词替换)
- **图像**:对 "Xiaomi SU7" 图像进行旋转操作(纯几何变换)
## 效果
在 MMEVOKE 基准上,知识无关增强产生**负面效果**
- 文本:-5.66% CEM-7.78% F1
- 图像:-47.36% CEM-12.76% F1
## 启示
表面操作无法增加语义知识——模型需要的不是"更多数据",而是**更深的理解**。这一发现对传统数据增强策略在知识注入场景中的适用性提出了根本性质疑。
