This study presents a comparison study on a reduced data using Analysis of Variance (ANOVA) and Recursive Feature Elimination (RFE) feature selection dimension reduction techniques, and evaluates the relative performance evaluation of classification procedures of Support Vector Machine (SVM) classification ...
The research introduces sixteen features (two carried forward) based on wavelet bi-phase (WBP) and bi-spectrum (WBS). The feature extraction step follows the calculation of probability histograms, and then features are ranked by ANOVA. The research employs decision tree, SVM, k-NN, NN, and ...
Method This paper presents the influence of One-way ANOVA and Kruskal-Wallis feature ranking techniques on the performance of four ML classifiers, namely, Decision Tree, SVM, KNN, and ANN for fault classification in a ball bearing. For this, two open data sources of Case Western Reserve ...
