该题目来自于Kaggle:Titanic: Machine Learning from Disaster,也是Kaggle上最受关注的题目之一,不仅因为它浪漫的背景故事,更因为数据集的一些feature也蛮耐人琢磨。最近struggle出一个模型,在此跟大家分享,其中kaggle上的一些算法也给予了我一些启发。 分析语言采用的R,特征工程的灵感主要来自于画图和统计检验,最终模型用...

EDA(Experimental Data Analysis)之常见分析方法总结--以kaggle的泰坦尼克号之灾为例 先引入包,一般EDA需要引入如下包: View Code 2.读入数据,一般使用data = pd.read_csv('filepath/file.csv')读取 3.正式开始EDA 看看数据的格式: data.head() 2.看看数据的各个字段有多少个为null的记录 data.isnull().sum...
To conduct our study, we focus on the Credit Card Fraud Detection Dataset, a set of anonymized financial transactions available on Kaggle [12]. This dataset is the only publicly available large data for credit card fraud analysis. Hence the scope of the study is limited to one dataset. With...
Data science projects mostly start with a business question or problem. A problem triggers an initiation phase, in which a set of possible solutions is defined, and initial feasibility is assessed. Initial data collection or an exploratory data analysis of available data is done to see what is...
