Scikit Learn: 在python中机器学习
参考: sklearn 数据集认识: sklearn中的iris数据集有5个key: [‘target_names’, ‘data’, ‘target’, ‘DESCR’, ‘feature_names’] target_names : 分类名称 [‘setosa’ ‘versicolor’ ‘virginica’] target:分类(150个) (150L,) [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2] feature_names: 特征名称 (‘feature_names:’, [‘sepal length (cm)’, ‘sepal width (cm)’, ‘petal length (cm)’, ‘petal width
