LASSO was used for AI features selection. TRAIL combines the clinical and selected AI features via a linear classification model. TRAIL was compared to two post-RP models; CAPRA-S, a purely clinicopathologic model trained to predict BCR post-RP, and a new model we created termed TRAIL-S ...
Using lasso penalization, these methods add penalties (L1 or L0 norm) to better guide the feature selection and model fitting process and achieve improved classification by allowing to select a subset of the covariates instead of using all of them....
whereas nonsignificant variables are automatically eliminated from the model. For some calculations, Ridge regression was used because, unlike Lasso regression, it generally assumes that all independent variables play an important role in explaining

Although the CPH model has been widely adopted by the scientific community2,4due to its ease of use, fast computation, and—most importantly—meaningful output, it inherently presents a few shortcomings. For instance, it is an inadequate model for high dimensional settings (i.e., when the num...
l1/2 algorithm is a improved variant algorithm of lasso. Similar with the method for solving lasso, i.e., iterated ridge regression.The way for solving this non-convex regularization framework is to transform it to iterated lasso or ridge regression. Reference: Xu, Z., Chang, X., Xu, ...
for the different possible changes in non-covalent lasso threading denoted\(k=\{{{\mathrm{0,1,2,3,4}}}\}\)of 0.1 or greater over the final 100 ns of the trajectory, or (iii) both (i) and (ii) occur (see “Methods”). Conditions (i) and (ii) correspond to perturbations...
We will use the term “non-TFU” and “ordinary units” interchangeably. We have also checked that there is no “penthouse” in our sample. On the other hand, we cannot rule out the “structural differences” (such as higher ceilings or bigger windows) that are unobservable to researchers...
use of the remaining eight species with particularly strong support (Σωi > 0.5) for the lesser anteater, armadillo, and white-tailed deer. Distance to nearest forest patch had the greatest influence on raccoon and capybara habitat use (Σωi > 0.66), with positive and negative ...
