剩下关联性低的数据中,如果多个特征之间关联性高,可以从中选一个特征加入train data。 缺失较多(例如超过50%)的特征数据需要从train data中删除,哪怕与target关联性(correlation在所有特诊中排第三,当然其数值可能就就0.4)很高。假设数据集中有100+条特征且平均correlation大于0.5,那么个人认为correlation小于0.05的特征...

#We imported a couple of packages. Let's create some sample data and add the line to this file: input_data = np.array([[3, -1.5, 3, -6.4], [0, 3, -1.3, 4.1], [1, 2.3, -2.9, -4.3]]) 我们现在准备对这些数据进行操作。
1. Quantitative Data Analysis This type of Data Analysis leans more toward the statistical nature of your data. It generally tells you what is happening and whether the trends are showing a rise or fall. Below are the types of Quantitative Data Analysis: ...
The Python pandas package is used for data manipulation and analysis, designed to let you work with labeled or relational data in an intuitive way. The panda…
explore your data visually and find the best representation of it. You learn as you go, add more data if needed, and ultimately get deeper insights. We call this the cycle of visual analysis. When you’ve gone through this cycle you can communicate a much better story about your data. ...
