它说是Mean squared error regression loss,并没有说它是否定的。 如果我查看源代码并检查了那里的示例:https://github.com/scikit-learn/scikit-learn/blob/a24c8b46/sklearn/metrics/regression.py#L183,它正在执行正常的mean squared error,即越小越好。 因此,我想知道我是否遗漏了关于文件中否定部分的任何内容。
摘要: For a suitably chosen ridge penalty parameter, the ridge regression estimator uniformly dominates the maximum likelihood regression estimator in terms of the mean squared error. Analogous results for the ridge maximum likelihood estimators of covariance and precision matrix are presented....
Ridge regularization for Mean Squared Error Reduction in Regression with Weak Instruments In this paper, I show that classic two-stage least squares (2SLS) estimates are highly unstable with weak instruments. I propose a ridge estimator (ridge IV) and show that it is asymptotically normal even ...
