The validity of the out-of-sample error estimate holds either under a strong convexity assumption, or for the L1-penalized Huber M-estimator and the Lasso under a sparsity assumption and a bound on the number of contaminated observations. For the square loss and in the ...
In sample error: training error, validation error and testing error. Out of sample error, or generalization error, is a measure of how accurately an algorithm is able to predict outcome values for previously unseen data. Because learning algorithms are evaluated on finite samples, the evaluation ...

Out-of-sample prediction is the acid test of predictive models, yet an independent test dataset is often not available for assessment of the prediction error. For this reason, out-of-sample performance is commonly estimated using data splitting algorithms such as cross-validation or the bootstrap...
I saw a lot of error messages about "Error on ingesting out-of-order samples" & "duplicate sample for timestamp" Environment System information: Linux 4.18.0-240.22.1.el8_3.x86_64 x86_64 Prometheus version: both are v1.8.2-0.20220106152233-4727c41a4b32 ...
(Original title: "Poor fit with absolute-error-like objective functions") I've looked more into the problem I described in this discussion post, and I think there are two underlying problems, one easy to solve or work around, and one not so easy. The easy part is that min_child_weight...

In RR the tuning parameter determining the penalty strength is usually obtained by minimizing some measure of the out-of-sample prediction error or information criterion. However, in presence of separation tuning these measures can yield ... H Inkovec,A Geroldinger,G Heinze,... 被引量: 0发表...
