摘要

This study proposes a novel approach utilizing a recently developed empirical statistical method to address redundancy in source imaging problems. This methodology integrates time and frequency domain analyses, leveraging a 3D tensor-based Canonical Polyadic Decomposition with wavelet transform. The approach is validated using epileptic EEG data, with hyperparameters optimized through K-fold cross-validation. The proposed method is benchmarked against state-of-the-art techniques across three test cases. It also improves the interpretability of epileptic EEG data and delivers robust, explainable results.
