The different steps of input construction: (a) The experimental EEG channel layout. (b) EEG channel matrix disposition to form 2D and 3D inputs (upper and lower images, resp.). Gray cells contain no information. (c) Usual 2D input shape and proposed 3D input shape following our considerations (upper and lower images, resp.).
