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=0.0) #实例化 var = VarianceThreshold(threshold=1.0) #删除特征值是1 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:
