The present study examines the role of feature selection methods in optimizing machine learning algorithms for predicting heart disease. The Cleveland Heart disease dataset with sixteen feature selection techniques in three categories of filter, wrapper, and evolutionary were used. Then seven algorithms Ba...
Product configuration is a feature selection process, taking a feature model fm as input and producing a feature configuration fc that is permitted by fm as output according to variability constraints. This can be reduced to a multistep configuration problem, i.e., the process of producing a se...
In summary, we identified a 38 gene signatures with ideal performance when classifying COAD tumor from normal samples by using feature selection methods in this study. The majority of the 38 DEGs were significantly up-regulated in tumor samples compared to normal samples. In the Bayesian network,...
Forman (2003) and Yang and Pedersen (1997) conducted evaluations of filter feature selectors and found that CS is among the most effective methods of feature selection for classification. Chi-Square is defined as Eq. (14): (14)χ2(Fj,C)=∑i=1b(Fj)∑c=1nClassN∗(wz−yx)2(w+y)...
In radiomics, different feature normalization methods, such as z-Score or Min–Max, are currently utilized, but their specific impact on the model is unclear. We aimed to measure their effect on the predictive performance and the feature selection. We em
We performed a systematic evaluation of twelve feature selection methods for preserving cellular trajectories in noisy single-cell data. Methods were grouped into five general categories prior to evaluation: supervised, similarity, subspace-learning, variance, and baseline approaches. For more details on ...
Surprisingly, the regions where ideal HCT succeeds and fails make exactly the same partition of the phase diagram. Other threshold methods, such as false (feature) discovery rate (FDR) threshold selection, are successful in a substantially smaller region of the phase space than either HCT or ...
