The classification of motor imagery response: an accuracy enhancement through the ensemble of random subspace k-NN

Mamunur Rashid, Bifta Sama Bari, Md Jahid Hasan, Mohd Azraai Mohd Razman, Rabiu Muazu Musa, Ahmad Fakhri Ab Nasir, Anwar P P Abdul Majeed
2021 PeerJ Computer Science  
The common spatial pattern (CSP) has been applied to extract the features from the MI response, and the effectiveness of random forest (RF)-based feature selection algorithm has also been investigated.  ...  The performance of BCIs primarily depends on the efficacy of the feature extraction and feature selection techniques, as well as the classification algorithms employed.  ...  Conversely, evolutionary algorithms (EA) can provide a potential solution by allowing the selection of features based on optimising the system's classification accuracy.  ...
