# HARS调和适应保留评分
## 定义
HARSHarmonized Adaptation-Retention Score是 [[kore-knowledge-injection|KORE]] 提出的**统一评估指标**,将[[knowledge-adaptation|知识适应]]和[[knowledge-retention|知识保留]]整合为单一调和分数,类似 F1 平衡 Precision 和 Recall。
## 公式
HARS = 2 · (f_A · f_R) / (f_A + f_R)
其中:
- f_A = G_A / (G_A + 100) × 100归一化适应分数
- f_R = G_R + 100归一化保留分数
- G_A = (K.A - K.A_0) / K.A_0适应相对增益
- G_R = (K.R - K.R_0) / K.R_0保留相对增益
- K.A_0, K.R_0预训练模型的基准表现
## 意义
知识注入方法常面临"适应-保留"权衡——提升一方面往往以牺牲另一方面为代价。HARS 提供了一个**单一数值**来衡量方法的整体平衡性,而非分散在多个指标中难以比较。
