## Definition
通过加权公式自动评估和推荐优质产品的算法模型,综合考虑销量、评分、评论数量、折扣等多个维度。
## Formula
```
score = sold × 0.4 + rating × 12 + rating_count × 0.2 + discount_percent × 0.5
```
## Parameters
| 参数 | 权重 | 说明 |
|------|------|------|
| sold | 0.4 | 销量,最核心的选品指标 |
| rating | 12 | 评分,反映产品质量 |
| rating_count | 0.2 | 评分数量,反映口碑积累 |
| discount_percent | 0.5 | 折扣力度,反映促销效果 |
## Use Cases
