Optimal Statistical Feature Subset Selection for Bearing Fault Detection and Severity Estimation

<div>Pairwise scatter plots for the top 3 ranked features. (a) Between T27 and T30. (b) Between T22 and T27. (c) Between T22 and T30. Here T22, T27, and T30 are rate of zero crossing, Hjorth parameter—mobility, and normal negative log likelihood for single Gaussian, respectively.</div>
