TL;DR
This paper introduces TFSSA, a novel feature selection algorithm based on a variant of SSA with Tent and Lévy strategies, demonstrating superior accuracy and fewer features in COVID-19 data classification.
Contribution
The paper presents TFSSA, a new hybrid algorithm combining Tent and Lévy strategies with SSA for effective feature selection in high-dimensional datasets.
Findings
TFSSA outperforms nine existing algorithms on 21 UCI datasets.
TFSSA achieves an average classification accuracy of 93.47% on COVID-19 data.
TFSSA selects an average of 2.1 features, reducing complexity.
Abstract
The "Curse of Dimensionality" induced by the rapid development of information science, might have a negative impact when dealing with big datasets. In this paper, we propose a variant of the sparrow search algorithm (SSA), called Tent L\'evy flying sparrow search algorithm (TFSSA), and use it to select the best subset of features in the packing pattern for classification purposes. SSA is a recently proposed algorithm that has not been systematically applied to feature selection problems. After verification by the CEC2020 benchmark function, TFSSA is used to select the best feature combination to maximize classification accuracy and minimize the number of selected features. The proposed TFSSA is compared with nine algorithms in the literature. Nine evaluation metrics are used to properly evaluate and compare the performance of these algorithms on twenty-one datasets from the UCI…
