Biomedical Engineering

Background:

Motor imagery (MI) electroencephalography (EEG)-based brain-computer interfaces (BCIs) show potential for neurorehabilitation.
Current BCIs face challenges with lengthy per-user calibration and inconsistent performance.

Purpose of the Study:

To enhance subject-dependent MI classification accuracy using transfer learning.
To reduce the need for extensive user-specific calibration data.

Main Methods:

Proposed Maximizing Single-Feature Separability (MSFS), a regularization technique for transfer learning.
MSFS leverages labeled data from other subjects within the same dataset.
Implemented MSFS using a silhouette-based separability criterion in a GPU-friendly manner.

Main Results:

MSFS consistently improved transfer learning performance across BCI Competition datasets and backbone networks.
The method remained competitive against existing transfer learning algorithms.
Ablation studies and few-shot experiments validated MSFS effectiveness, especially with limited target subject data.

Conclusions:

MSFS offers a practical within-dataset transfer learning solution for MI EEG decoding.
The approach improves target-subject accuracy with reduced calibration data.
MSFS is easily integrated into existing deep learning pipelines for MI BCIs.
