Area of Science:

  • Neuroscience
  • Quantum Computing
  • Machine Learning

Background:

  • Low transfer rates in electroencephalography (EEG) brain-computer interfaces (BCIs) necessitate advanced classifiers.
  • Quantum classification and case-based reasoning offer potential solutions for improved EEG data analysis.

Purpose of the Study:

  • To evaluate the performance of variational quantum, quantum-enhanced support vector, and hypergraph case-based reasoning classifiers for binary classification of EEG data.
  • To assess the impact of simplified preprocessing on case-based reasoning performance.

Main Methods:

  • Binary classification of P300 experiment EEG data.
  • Implementation and comparison of variational quantum, quantum-enhanced support vector, and hypergraph case-based reasoning classifiers.
  • Analysis of balanced training and prediction accuracy.

Main Results:

  • Balanced training accuracies were 56.95%, 83.17%, and 71.10% for the respective classifiers.
  • Prediction accuracies were 51.83%, 50.25%, and 52.04%.
  • Case-based reasoning with simplified preprocessing yielded 49.78% accuracy, indicating a significant performance drop.

Conclusions:

  • All tested classifiers demonstrated the ability to learn from EEG data, and quantum classification is implementable.
  • Current prediction accuracies are insufficient for practical BCI applications due to poor generalization.
  • Future improvements require enhanced quantum classifier configurations and transfer learning for case-based reasoning.
