## Module 2: 机器学习预测器
|
||||
|
||||
### 功能特性
|
||||
|
||||
- ✅ **模型训练**: XGBoost分类器,准确率约73%
|
||||
- ✅ **特征工程**: 年龄转换、BMI计算、异常值处理
|
||||
- ✅ **RESTful API**: Flask提供预测接口
|
||||
- ✅ **前端界面**: 交互式Web表单,实时预测
|
||||
- ✅ **模型持久化**: Joblib保存完整Pipeline
|
||||
|
||||
### 模型训练
|
||||
|
||||
#### 1. 训练模型(一次性)
|
||||
```bash
|
||||
# 进入项目根目录
|
||||
cd D:\Project\PythonProject\AIcode\test
|
||||
|
||||
# 激活conda环境
|
||||
conda activate cardioenv
|
||||
|
||||
# 运行训练脚本
|
||||
python module2_predictor/train_and_save.py
|
||||
```
|
||||
|
||||
训练脚本将:
|
||||
1. 加载和清洗数据(与Module 1相同)
|
||||
2. 特征工程:年龄转换、BMI计算
|
||||
3. 构建机器学习Pipeline(StandardScaler + OneHotEncoder + XGBoost)
|
||||
4. 训练模型并评估性能
|
||||
5. 保存模型到 `module2_predictor/models/cardio_predictor_model.pkl`
|
||||
|
||||
#### 2. 模型特征
|
||||
- **连续特征**: age_years, bmi, ap_hi, ap_lo
|
||||
- **分类特征**: gender, cholesterol, gluc
|
||||
- **二元特征**: smoke, alco, active
|
||||
|
||||
**Top 5 重要特征**:
|
||||
1. 收缩压 (ap_hi)
|
||||
2. 极高胆固醇 (cholesterol_3)
|
||||
3. 年龄 (age_years)
|
||||
4. 舒张压 (ap_lo)
|
||||
5. 极高血糖 (gluc_3)
|
||||
|
||||

|
||||
|
||||
#### 1. 启动API服务
|
||||

|
||||
|
||||
# 方法1: 直接运行Python脚本
|
||||
python module2_predictor/app.py
|
||||
|
||||
# 方法2: 使用Flask CLI
|
||||
set FLASK_APP=module2_predictor/app.py
|
||||
flask run --host=0.0.0.0 --port=5000
|
||||
|
||||
# 方法3: 使用conda直接运行
|
||||
"D:\software\anaconda\Scripts\conda.exe" run -n cardioenv python module2_predictor/app.py
|
||||
```
|
||||
|
||||

**症状**: 训练脚本报错或无法保存模型
|
||||
**解决**:
|
||||
1. 检查数据文件路径是否正确
|
||||
2. 确保有足够的磁盘空间
|
||||
3. 检查Python依赖包是否完整安装
|
||||
|
||||
#### Q2: Flask应用无法启动
|
||||
**症状**: 启动时出现导入错误或模型加载失败
|
||||
**解决**:
|
||||
1. 检查conda环境是否激活
|
||||
2. 确保模型文件存在:`module2_predictor/models/cardio_predictor_model.pkl`
|
||||
3. 检查端口5000是否被占用
|
||||
|
||||
#### Q3: 预测结果不合理
|
||||
**症状**: 预测概率总是0或1,或与预期不符
|
||||
**解决**:
|
||||
1. 检查输入数据是否在合理范围内
|
||||
2. 验证特征预处理是否正确
|
||||
3. 确保模型训练时使用了正确的特征
|
||||
|
||||
#### Q4: 前端界面无法访问
|
||||
**症状**: 浏览器显示连接错误
|
||||
**解决**:
|
||||
1. 确认Flask应用正在运行
|
||||
2. 检查防火墙设置,允许端口5000
|
||||
3. 尝试访问 `http://localhost:5000/health` 检查服务状态
|
||||
|
||||
### 下一步开发
|
||||
|
||||
1. **模型优化**: 尝试其他算法(LightGBM, CatBoost)和超参数调优
|
||||
2. **特征扩展**: 添加更多临床特征(家族史、药物治疗等)
|
||||
3. **API增强**: 添加批量预测、模型版本管理
|
||||
4. **监控告警**: 添加性能监控和异常告警
|
||||
5. **部署优化**: Docker容器化,云平台部署
