In this study, five importance-based feature selection methods were employed: XGBoost [22], Decision Tree (DT) [7], CatBoost [8], Extremely Randomized Trees (ET) [9], and Random Forest (RF) [10]. XGBoost and CatBoost stand out as widely used gradient boosting algorithms, each employing ...
Feature Selection Using Random Forest Tree-based machine learning algorithms likeDecisionTreeClassifieror their ensemble learning equivalentRandomForestClassifieruses a set of trees which contains nodes resulting from splitting. The main aim of those splits is to decrease impurity as much as possible by ...
feature selection algorithms. Two of the algorithms, Trank and Wrank, are from the Python scipy package, and all the other algorithms are from the Python scikit-learn package. Wrapper algorithms may achieve differently using different parameters. We assume that the default parameters of a wrapper ...

Gene feature selection using SNR-PPFS algorithms After obtaining the gene expression dataset of 637 samples, we subsequently performed feature selection to identify gene signatures as classifier between tumor and normal groups. As shown in Fig. 1, the gene feature selection process consisted primarily...
We implemented both methods using Python3 scikit-learn 0.19.2 library46. See Supplementary Methods for descriptions of the algorithms and implementation details. Feature selection With a total of 18485 biological features that can be used to describe the cancer cell lines, the analyzed dataset is ...
