一直想着抓取股票的变化,偶然的机会在看股票数据抓取的博客看到了kaggle,然后看了看里面的题,感觉挺新颖的,就试了试. 题目如图:给了一个train.csv,现在预测test.csv里面的Passager是否幸存.train.csv里面包含的乘客信息有 PassagerId 乘客id Survived 乘客是否幸存 Pclass 仓位 Name 乘客姓名 Sex 乘客性别 Age 乘客年龄 SibSp 船上是否有兄弟姐妹 Parch 穿上是否有父母子女 Ticket 船票信息 Fare 票价…

 下面一文章就总结几点关键: 1.要学会观察,尤其是输入数据的特征提取时,看各输入数据和输出的关系,用绘图看! 2.训练后,看测试数据和训练数据误差,确定是否过拟合还是欠拟合: 3.欠拟合的话,说明模型不准确或者特征提取不够,对于特征提取不够问题,可以根据模型的反馈来看其和数据的相关性,如果相关系数是0,则放弃特征,如果过低,说明特征需要再次提炼! 4.用集成学习,bagging等通常可以获得更高的准确度! 5.缺失数据可以使用决策树回归进行预测! 转自:http://blog.csdn.net…

泰坦尼克号幸存预测是本小白接触的第一个Kaggle入门比赛,主要参考了以下两篇教程: https://www.cnblogs.com/star-zhao/p/9801196.html https://zhuanlan.zhihu.com/p/30538352 本模型在Leaderboard上的最高得分为0.79904,排名前13%. 由于这个比赛做得比较早了,当时很多分析的细节都忘了,而且由于是第一次做,整体还是非常简陋的.今天心血来潮,就当做个简单的记录(流水账). 导入相关包: import…
