In this article a classificationand regression trees (CART) based feature selectionalgorithm has been proposed which offers optimumset of features. Further optimum set of features hasbeen offered by our proposed work passed over variousclassifiers for training and testing to establishnetwork intrusion ...
BorutaShap is a wrapper feature selection method which combines both the Boruta feature selection algorithm with shapley values. This combination has proven to out perform the original Permutation Importance method in both speed, and the quality of the feature subset produced. Not only does this algo...
Feature (variable) selection methods are used to detect the most important features (variables) within high-dimensional data. Tree-based models, such as Random Forests, are often exploited for this purpose, as they provide a built-in mechanism to quantify feature importance. However, the ...

Feature selection using the Boruta algorithm. Full size image Comparing the estimated predictive power indices in Table 1 shows that the gmerf model has resulted in the best performance among the evaluated models (AUC (0.95% CI) = 0.80 (0.77,0.84)). The glmm tree model was ranked second...
FDT-SVM incorporates effective techniques for feature selection (FS) and class grouping (CG) at each non-leaf nodes of the tree structure, which reduce the overall complexity of DT building and alleviate the overfitting effect. The embedded FS and CG are based on the notion of fuzzy partition...
