Biomedical Engineering

Background:

Brain-computer interfaces (BCI) use electroencephalography (EEG) for device interaction.
Generic EEG models face challenges due to signal non-stationarity and individual variations.
Transfer learning (TL) reduces calibration needs in BCI by transferring knowledge between subjects.

Purpose of the Study:

To propose a novel Manifold Embedded Transfer Learning (METL) framework for motor imagery (MI) EEG decoding.
To leverage geometric properties of Riemann manifolds and joint distribution adaptation for improved EEG signal classification.
To address the limitations of conventional methods in EEG-based BCI applications.

Main Methods:

Aligning EEG trial covariance matrices on the Symmetric Positive Definite (SPD) manifold.
Extracting features from both SPD and Grassmann manifolds.
Learning classification models using structural risk minimization and joint distribution alignment.

Main Results:

METL demonstrated effective performance on two MI EEG datasets.
Achieved more accurate and stable classification, particularly with limited target domain data.
Outperformed conventional methods in single-to-single (STS) and multi-to-single (MTS) transfer tasks.

Conclusions:

METL effectively handles single and multi-source domains, with multi-source learning enhancing performance.
The framework achieves superior classification performance for EEG signals.
METL offers a robust solution for EEG-based BCI applications.
