    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Signal Processing

    Background:

    • Motor imagery brain-computer interfaces (MI-BCIs) using electroencephalogram (EEG) are gaining traction due to their portability and low cost.
    • Effective extraction of frequency components from multi-channel EEG is crucial for advancing MI-BCI performance.
    • Current feature extraction methods often fall short in fully exploiting the rich frequency information present in EEG signals.

    Purpose of the Study:

    • To propose and evaluate a novel method, tensor-based frequency feature combination (TFFC), for enhanced frequency information extraction in MI-BCI systems.
    • To demonstrate the effectiveness of TFFC in improving classification accuracy compared to existing state-of-the-art feature extraction techniques.
    • To provide insights into the generalization capabilities of TFFC and the complementarity of different frequency features.

    Main Methods:

    • Developed the tensor-based frequency feature combination (TFFC) method, integrating tensor-to-vector projection (TVP), fast Fourier transform (FFT), common spatial pattern (CSP), and feature fusion.
    • Validated TFFC using two independent EEG datasets and compared its performance against established feature extraction methods.
    • Employed various classifiers to assess the robustness and generalizability of the proposed TFFC feature set.

    Main Results:

    • The TFFC method consistently improved classification accuracy by approximately 5% across different classifiers and datasets.
    • Visualization analysis indicated that TFFC generalizes established methods like CSP and Filter Bank CSP (FBCSP).
    • Observed a significant complementarity between weighted narrowband features (wNBFs) and broadband features (BBFs) within the TFFC framework.

    Conclusions:

    • The TFFC method offers a robust and effective approach for extracting frequency information from EEG signals in MI-BCI systems.
    • TFFC represents a significant advancement, providing a generalized framework that encompasses and potentially surpasses existing CSP-based methods.
    • This work highlights the critical importance of comprehensive frequency feature analysis and suggests new avenues for MI-EEG feature set design.
