    This study introduces a Bayesian approach for classifying electroencephalography (EEG) patterns from imaginary movements, demonstrating competitive performance against established methods. Eye movement artifacts were found to not impact classification accuracy in Brain-Computer Interface (BCI) applications.

    Area of Science:

    • Neuroscience
    • Machine Learning
    • Signal Processing

    Context:

    • Brain-Computer Interfaces (BCI) are crucial for assistive technologies.
    • Electroencephalography (EEG) is a common modality for BCI.
    • Classification of EEG patterns, especially from motor imagery, is a key challenge.

    Purpose:

    • To propose and evaluate a Bayesian approach for classifying EEG patterns associated with imaginary limb movements.
    • To assess the efficacy of this Bayesian classifier within a BCI system.
    • To investigate the impact of eye movement and blinking artifacts on BCI performance.

    Summary:

    • A Bayesian classifier was developed for EEG pattern recognition based on covariance matrix analysis of imaginary limb movements.
    • The proposed Bayesian method demonstrated competitive performance compared to the Multiclass Common Spatial Patterns (MCSP) classifier.
