Abstract
A motor imagery-based brain-computer interface (MI-BCI) creates a path through which the brain interacts with the external environment by recording and processing electroencephalograph (EEG) signals made by imagining the movement of a particular limb. In this study, with the aim of improving classification accuracy, we modified the feature extraction stage. After preprocessing and decomposing EEG signals into their frequency ...
