sklearn.model_selection.learning_curve学习曲线 这个函数的作用为:对于不同大小的训练集,确定交叉验证训练和测试的分数。一个交叉验证发生器将整个数据集分割k次,分割成训练集和测试集。不同大小的训练集的子集将会被用来训练评估器并且对于每一个大小的训练子集都会产生一个分数,然后测试集的分数也会计算。然后,...
使用sklearn.model_selection.learning_curve绘制学习曲线,并判断模型学习情况(欠拟合/过拟合),程序员大本营,技术文章内容聚合第一站。
from sklearn.model_selection import learning_curve 参数解释:参考:https://blog.csdn.net/gracejpw/article/details/102370364 image X :array-like, shape (n_samples, n_features) Training vector, where n_samples is the number of samples and n_features is the number of features. ...
