Coupled Dictionary Learning for Unsupervised Feature Selection
WebSep 11, 2024 · How does correlation help in feature selection? Features with high correlation are more linearly dependent and hence have almost the same effect on the dependent variable. So, when two features have … WebJan 15, 2024 · The coupled feature selection strategy proposed in the paper has been proven to be superior to the singular feature selection method in Section 3.2. Based on … Webcoupled feature selection. To achieve this goal, we propose a generic minimization formulation by coupled linear re-gressions, 21-norm and trace norm, which will be detailed in the next section. 3.
