Summary

This special issue examines the critical role of advanced feature selection algorithms in enhancing the efficacy of machine learning models. Feature selection is pivotal in the machine learning pipeline, significantly influencing model performance by improving accuracy, reducing computational complexity, enhancing interpretability, and mitigating overfitting. However, the growing complexity and volume of data necessitate innovative solutions to efficiently and effectively select relevant features.


The research in feature selection faces several significant challenges. Traditional methods may struggle with high-dimensional data, and the emergence of new data types and structures demands more sophisticated techniques. Moreover, the need for interpretable and explainable models in various domains further underscores the importance of robust feature selection methods. This special issue aims to:

· Explore innovative algorithms and techniques for feature selection.

· Assess the effectiveness of these techniques in diverse applications.

· Foster interdisciplinary collaboration among researchers, practitioners, and policymakers.


We especially encourage submissions that present novel methodologies, evaluate their performance in real-world scenarios, and propose practical frameworks for enhancing machine learning models through effective feature selection. We welcome original research articles, review papers, and case studies. The special issue solicits original research articles, reviews, and case studies that cover, but are not limited to, the following topics:

· Hybrid and ensemble feature selection techniques

· Scalable algorithms for high-dimensional and big data feature selection

· Domain-specific feature selection methods (e.g., text, bioinformatics, computer vision)

· Interpretable and explainable feature selection approaches

· Automated and meta-learning approaches to feature selection

· Quantum computing and other emerging paradigms for feature selection

· Federated and privacy-preserving feature selection techniques

· Benchmarking and comparative studies of feature selection algorithms

· Real-world applications and case studies of advanced feature selection methods

    Abstract Inertial Sensor-based Daily Activity Recognition (IS-DAR) requires adaptable, data-efficient methods for effective multi-sensor use. This study presents an advanced detection system using body-worn sensors to accurately recognize activities. A structured pipeline enhances IS-DAR by applying signal preprocessing, feature extraction and optimization, followed by classification. Before segmentation, a Chebyshev filter removes noise, and Blackman windowing improves signal representation. Discriminative features—Gaussian Mixture Model (GMM) with Mel-Frequency Cepstral Coefficients (MFCC), spectral entropy, quaternion-based features, and Gammatone Cepstral Coefficients (GCC)—are fused to expand the feature space. Unlike existing approaches, the proposed IS-DAR system uniquely integrates diverse handcrafted features using… More >

    Abstract Advanced Persistent Threats (APTs) represent one of the most complex and dangerous categories of cyber-attacks characterised by their stealthy behaviour, long-term persistence, and ability to bypass traditional detection systems. The complexity of real-world network data poses significant challenges in detection. Machine learning models have shown promise in detecting APTs; however, their performance often suffers when trained on large datasets with redundant or irrelevant features. This study presents a novel, hybrid feature selection method designed to improve APT detection by reducing dimensionality while preserving the informative characteristics of the data. It combines Mutual Information (MI), Symmetric… More >

    Abstract Unmanned Aerial Vehicles (UAVs) are increasingly employed in traffic surveillance, urban planning, and infrastructure monitoring due to their cost-effectiveness, flexibility, and high-resolution imaging. However, vehicle detection and classification in aerial imagery remain challenging due to scale variations from fluctuating UAV altitudes, frequent occlusions in dense traffic, and environmental noise, such as shadows and lighting inconsistencies. Traditional methods, including sliding-window searches and shallow learning techniques, struggle with computational inefficiency and robustness under dynamic conditions. To address these limitations, this study proposes a six-stage hierarchical framework integrating radiometric calibration, deep learning, and classical feature engineering. The workflow… More >

    Abstract Grains are the most important food consumed globally, yet their yield can be severely impacted by pest infestations. Addressing this issue, scientists and researchers strive to enhance the yield-to-seed ratio through effective pest detection methods. Traditional approaches often rely on preprocessed datasets, but there is a growing need for solutions that utilize real-time images of pests in their natural habitat. Our study introduces a novel two-step approach to tackle this challenge. Initially, raw images with complex backgrounds are captured. In the subsequent step, feature extraction is performed using both hand-crafted algorithms (Haralick, LBP, and Color… More >

    Abstract Feature selection methods rooted in rough sets confront two notable limitations: their high computational complexity and sensitivity to noise, rendering them impractical for managing large-scale and noisy datasets. The primary issue stems from these methods’ undue reliance on all samples. To overcome these challenges, we introduce the concept of cross-similarity grounded in a robust fuzzy relation and design a rapid and robust feature selection algorithm. Firstly, we construct a robust fuzzy relation by introducing a truncation parameter. Then, based on this fuzzy relation, we propose the concept of cross-similarity, which emphasizes the sample-to-sample similarity relations… More >
