、、、 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2...
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...
ImportError: cannotimportname'cross_validate' Everything else in Sklearn seems to work fine, it's just this bit. Error even occurs when I run this one line and nothing else. cross-validateis new in version 0.19.0 (change log): Cross validation is now able to return the results from mul...
cross函数pythoncross函数参数 在使用Pytorch时经常碰见这些函数cross_entropy,CrossEntropyLoss, log_softmax, softmax。首先要知道上面提到的这些函数一部分是来自于torch.nn,而另一部分则来自于torch.nn.functional(常缩写为F)。 下面是对与crossentropy有关的函数做的总结:torch.nntorch.nn.functional ...
