Titanic数据集可以在Kaggle网站上下载,或者通过直接链接获取CSV文件。在这里我们将使用R的read.csv函数直接读取数据。假设已经将数据集保存为titanic.csv文件。 2.3 读取数据集 使用以下代码读取Titanic数据集: # 读取Titanic数据集titanic_data<-read.csv("titanic.csv")# 查看数据集的前几行head(titanic_data) 1. ...
titanic数据集The data has been split into two groups: training set (train.csv) test set (test.csv) The training set should be used to build your machine learning models. For the training set, we provide the outcome (also known as the “ground truth”) for each passenger. Your model wil...

kaggle上还可以下载test集,我们把train集得到的结果进行预测,然后根据kaggle的格式要求进行上传,kaggle给了样例的上传要求,仅有两列,一列为PassengerId,一列为Survived,我们也根据这样去生成符合标准的CSV文件。 test=pd.read_csv('D:\\dataset\\Titanic-test.csv') ...
