一、背景 接上所叙,在对比训练集、验证集、测试集之后,实战中需要对数据进行划分。 通常将原始数据按比例划分为:训练集、测试集。 可以利用 sklearn.model_selection.train_test_split 方法实现。 二、介绍 使用语法为: 参数解释: 三、实操 ...
sklearn的train_test_split train_test_split函数用于将矩阵随机划分为训练子集和测试子集,并返回划分好的训练集测试集样本和训练集测试集标签。 格式: X_train,X_test, y_train, y_test ...
使用sklearn.model_selection.train_test_split可以在数据集上随机划分出一定比例的训练集和测试集 1.使用形式为: 2.参数解释: train_data:样本特征集 train_target:样本的标签集 test_size:样本占 ...
