array([3, 5]) Linspace和Arrange非常相似,但略有不同。Linspace以指定数目均匀分割区间,所以给定区间start和end,以及等分分割点数目num,linspace将返回一个NumPy数组。 这对绘图时数据可视化和声明坐标轴特别有用。 # np.linspace(start, stop, num)np.linspace...
data=pd.read_excel('textdata.xlsx')#指定参与衍生的变量名FEATURE_LIST=['ft','gt']#指定聚合月份P_LIST=[3,6]#调用变量衍生函数 gen=feature_generation(data,FEATURE_LIST,P_LIST)df=gen.fit_generate() 读到这里可能有的同学一头雾水。接下来详细的剖析一下这35种特征衍生方案。
