现在,结果应该是相似的,但还不完全相同。如果您在函数之前(以及函数外部)定义了kf = KFold(shuffle=False, random_state=0),并以相同的方式运行cross_validate,则可以将它们转换为相同 scores = cross_validate(RandomForestRegressor(), X_s, y_s, cv=kf, scoring='r2') # cv=kf i、 e.在这两种情况下...
在Python的scikit-learn库中，有`cross_validate`和`KFold`两个API用于实现交叉验证，名称上虽有交集，但功能和用途并不相同。`cross_validate` API主要提供计算交叉验证指标值并记录训练时间的工具，用于获取模型评估的统计结果。`KFold` API则专注于数据切分，将数据集按照K折要求进行分割，输出训练集和...
我有两个独立的python函数,其中一个使用cross_val_predict返回数据集的预测值,另一个使用cross_validate返回多个错误度量值。下面显示了用于获取度量值的方法(我已经实现了一个类似的方法来获得预测)。abs_error': 'neg_mean_absolute_error', 'squared_error': 'neg_mean_squared_error&#x 浏览6提问于2018-08-...
The training data used in the model is split, into k number of smaller sets, to be used to validate the model. The model is then trained on k-1 folds of training set. The remaining fold is then used as a validation set to evaluate the model....
