Hybrid-Recursive Feature Elimination for Efficient Feature Selection

Abstract: As datasets continue to increase in size, it is important to select the optimal feature subset from the original dataset to obtain the best performance in machine learning tasks. Highly dimensional datasets that have an excessive number of features can cause low performance in such tasks. Overfitting is a typical problem. In addition, datasets that are of high dimensionality can create shortages in space and require high computing power, and models fitted to such datasets can produce low classification accurac… Show more

“…Feature selection is more important to select a good subset of features in many fields including finance, production, manufacturing, medicine, image processing, and biology. The recursive feature elimination (REF) is a technique for the selection of the best subset of optimal features, in the past study many researchers investigate and used [ 54 , 55 , 56 , 57 , 58 , 59 , 60 ]. In this study, we used the recursive feature elimination (RFE) technique to select the optimal feature subset for the classification of COPD patients.…”

“…Once our algorithms have been evaluated, we perform RFE on the original dataset and compute the above metrics. Various works [77]- [80] regarding FS, have considered RFE as a benchmark FS algorithm, thereby making it a yardstick for comparison. Moreover, RFE behaves like a Hybrid FS model as it ranks the attributes based on feature importances, and then recursively eliminates the worst feature according to the ranking.…”

“…Considering HDLSS data, reducing the number of features is crucial to perform nonoverparameterized classification-based analyses [54]. Feature selection techniques can be classified into filter, wrapper, and embedded methods [53].…”
