实验说明:
|
||||||
|
- 自行编写实现数据加载与预测病马死亡的对率回归算法。
|
||||||
|
|
||||||
|
注意事项:
|
||||||
|
- 在 function.py 中实现对率回归算法。
|
||||||
|
- 可以自行导入其他库,需要在 requirements.txt 添加依赖,若未在 requirements.txt 中添加使用到的依赖,则无法自动评测,成绩为零。
|
||||||
|
- 自动评测脚本仅会加载 train_logreg、predict_logreg 和 load_data 函数,请勿修改函数名。
|
||||||
|
|
||||||
|
