Core Methodology
The system integrates three key phases: comprehensive feature extraction, efficient feature reduction using Gray Wolf Optimization (GWO), and robust classification via a hybrid SVM-Fuzzy model trained with Goose Optimization (GOOSE). This multi-stage approach is designed for accuracy and computational efficiency.
Feature Extraction
Diverse features from EEG signals are extracted, including statistical (mean, variance, skewness, kurtosis, max, min, RMS), frequency-domain (IWMF, IWBW, PSD, Band Power), and nonlinear (Shannon, Log-Energy, Rényi, Tsallis entropies, Hjorth parameters: Activity, Mobility, Complexity). These 34 features per channel (total 646 for 19 channels) capture critical patterns for epileptic seizure detection.
Dataset Utilized
The model was trained and validated on the University of Beirut Medical Center (UBMC) dataset, comprising EEG recordings from six epileptic patients. This dataset includes nearly 7 hours of both ictal and interictal data from 19 surface electrodes (500 Hz sampling rate), providing 7011 training and 779 test samples segmented into 1-second windows.
Gray Wolf Optimization (GWO) for Feature Reduction
GWO is employed to optimize a feature reduction matrix, minimizing intra-cluster dispersion (D) and maximizing clustering quality (K). This reduces the initial 646 features to a compact set of 20-25, significantly cutting computational complexity while preserving critical discriminative information. This process is crucial for enabling real-time operation on low-resource hardware.
Hybrid SVM-Fuzzy Classification with GOOSE Optimization
A hybrid Support Vector Machine (SVM) and Fuzzy Inference System (FIS), structured on an ANFIS architecture (Takagi Sugeno fuzzy model), forms the core classifier. The SVM provides initial feature weighting, mapping high-dimensional data into a separable space. Goose Optimization (GOOSE) is used to train and optimize the fuzzy membership functions (Gaussian parameters) and SVM weights, minimizing classification error and ensuring robust performance across multi-class epileptic seizure detection.
Overall System Performance
The proposed SVM-Fuzzy system with GWO-based feature reduction achieved an impressive 98.1% accuracy, 97.8% sensitivity, and 98.4% specificity on the UBMC test dataset. This surpasses traditional machine learning methods and offers a robust, efficient solution for epileptic seizure detection, validated through 10-fold cross-validation.
Computational Efficiency
The optimized feature reduction from 646 to 20-25 features drastically reduces the computational burden, allowing for inference times of approximately 50–200ms per 1-second EEG window on standard CPUs. This is significantly faster than deep learning models (500–2000ms) and enables deployment on resource-constrained mobile and IoT devices.
Visual Validation (t-SNE & SHAP)
t-SNE visualization confirms that the GWO-optimized feature space creates tight, well-separated clusters for ictal and interictal samples, indicating successful preservation of discriminative information. SHAP analysis further highlights the importance of nonlinear (e.g., Tsallis wavelet entropy) and frequency features, which align with clinical understanding of seizure patterns.
