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

 

(1)Variance Threshold(threshold =0.0

 

 

(2)Variance Threshold(threshold =1.0

 

 

(3)Variance Threshold(threshold =2.0
