作业八 特征选择

用过滤法对以下数据进行特征选择:

                             [[0,2,0,3],

                              [0,1,4,3],

                              [0,1,1,3]]

要求:

1、Variance Threshold(threshold =1.0)

2、将结果截图

代码:

from sklearn.feature_selection import  VarianceThreshold
def var():
var =VarianceThreshold(threshold=1.0)
data=var.fit_transform([[0,2,0,3],[0,1,4,3],[0,1,1,3]])
print(data)
return None

if __name__ =="__main__":
var()
结果:
