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:
