使用LightGBM和GridSearchCV预测Titanic数据集

本文主要是介绍使用LightGBM和GridSearchCV预测Titanic数据集，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

对于Titanic数据集预测的初次尝试，主要使用的是LightGBM和GridSearchCV。这两个参数都很多，对应的文档在https://lightgbm.readthedocs.io/en/latest/Experiments.html 和 https://lightgbm.cn/docs/6/#io以及https://scikit-learn.org/stable/modules/generated/sklearn.model_selection.GridSearchCV.html
常看常新吧，毕竟官方文档是最好的指导老师。

未来改进：可变学习速率；训练信息提取储存；Cabin信息充分利用；算法调参

from sklearn.preprocessing import StandardScaler
from sklearn.metrics import roc_auc_scoredir=r'C:\Users\43480\Documents\python_work\Titanic'#写路径的时候，raw字符串可以用\，否则就需要用//。
train = pd.read_csv(dir+'//train.csv')
test = pd.read_csv(dir+'//test.csv')cate_cols = ['Sex', 'Embarked']
no_feas = ['PassengerId','Survived','Ticket','Name','Cabin']#理论上说，Cabin还是有利用价值的，这里是第一次用，就没管。
num_cols=train.columns.drop(no_feas).drop(cate_cols)#.drop()可以在不改变原对象内容的情况下生成新的对象。
y_train=train['Survived']#.astype(int)#这里很迷，理论上应该完全不影响的，但是有的时候需要，有的时候就不需要。

两个imputer的strategy都是最频繁，数字属性这里确实可以考虑换成中位数

num_pipeline=Pipeline([('imputer',SimpleImputer(missing_values=np.nan, strategy = 'most_frequent')),('std_scaler',StandardScaler()),
])
cate_pipeline=Pipeline([('imputer',SimpleImputer(missing_values=np.nan, strategy = 'most_frequent')),('onehotencoder',OneHotEncoder()),
])full_pipeline=ColumnTransformer([('num', num_pipeline,num_cols),('cate',cate_pipeline,cate_cols)
])
train_tr=full_pipeline.fit_transform(train)#train_tr即train_transformed
test_tr=full_pipeline.fit_transform(test)

查阅说明文档得知，bagging_fraction与subsample是同一个变量的不同名称，剩下三个的情况与此相同，之所以用一个不用另一个是因为用了就会不停地挑warning，原因不明。貌似就算数据集不平衡，开了is_unbalance也会导致预测结果变差，原因不明。

gsearch = GridSearchCV(gbm, params_grid, scoring=‘roc_auc’, cv=5,verbose=4,return_train_score=True)其中verbose>3才能够有详细的训练细节输出，return_train_score=True才能看到训练过程的得分，从而判断是否过拟合。
split0_train_score和split1_train_score是什么东西还没有搞懂。

从给出的score判断，现阶段模型处于过拟合状态（提交之后的得分也证实了这一点），解决过拟合需要调参，调参的基础是对于算法的深入理解，这也正是下一步的努力方向。

另外，未来很可能需要将 GridSearchCV的训练信息提取保存分析，出现需求的时候再说吧。
