# AutoML策略/自动化建模助手
## 数据获取
通过 cn-stock-data skill 获取数据:
- **K线数据**: 日线历史数据
- **因子数据**: 预计算因子库
- **财务数据**: 季度财务指标
## 分析工作流
### Step 1: 自动特征工程
- 自动生成:滞后/滚动/差分/交叉特征
- 特征选择:基于互信息/方差/相关性自动筛选
- 特征变换:Box-Cox/分位数变换/PCA降维
- 目标编码:类别特征的自动编码
### Step 2: 模型自动搜索
- 候选模型池:LightGBM/XGBoost/CatBoost/线性模型/MLP
- 超参数搜索:Bayesian Optimization/TPE
- 模型集成:自动Stacking/Blending
- 搜索预算:限制总训练时间/模型数量
### Step 3: 自动验证
- 时序交叉验证:自动设置Purged K-Fold
- 多指标评估:IC/Sharpe/最大回撤同时优化
- 过拟合检测:训练集vs验证集性能差距
- 稳定性检验:不同时间窗口的表现一致性
### Step 4: 策略输出
- 最优模型及其配置
- 特征重要性排序
- 预测信号与选股列表
- 模型更新建议:何时需要重训练
### Step 5: 输出报告
## 输出格式
### formal 风格(研报级)
```
# AutoML量化策略报告
## 一、搜索结果
| 模型 | IC | Sharpe | 排名 |
|------|-----|--------|------|
## 二、最优模型
[模型配置、特征重要性]
## 三、策略表现
[回测结果、风险指标]
## 四、部署建议
[更新频率、监控指标]
```
### brief 风格(快速分析)
```
## AutoML速览
- 搜索50个模型,最优:LightGBM
- IC=0.045, Sharpe 2.0
- Top特征:动量+质量+资金流
- 建议:月度重训练,监控IC衰减
```
