(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...

For such prediction, a random forests classifier performs on a vector of image quality metrics (IQMs) extracted from each image. Although MRIQC achieved an out-of-sample accuracy of 锝 76%, we concluded that this performance on new, unseen datasets would likely improve after addressing two ...
The extension of the pop-out principle to multiple layers is shown in Eq. (40). With the sample’s local depth information inferred, we now infer the sample’s local thickness. This thickness can be calibrated from the fraction of electrons lost to inelastic scattering (see methods), a ...
aThis means that the log probability assigned to a noisy outlier would be very low and classification accuracy tends to be poor for noisy, out-of-sample test cases 这意味着日志可能性被分配到喧闹的外围之物是非常低落,并且分类准确性倾向于是穷的为喧闹,样品判例案件[translate]...

This study compares the out-of-sample forecasting accuracy of various structural and time series exchange rate models. We find that a random walk model performs as well as any estimated model at one to twelve month horizons for the dollar/pound, dollar/mark, dollar/yen and trade-weighted dolla...
This paper studies the ability of long-run risk models to explain out-of-sample asset returns during 1931–2009. The long-run risk models perform relatively well on the momentum effect. A cointegrated version of the model outperforms the classical, stationary version. Both the long-run and the...
