Abstract
This paper presents classification methods for electroencephalography (EEG)
signals in imagination of direction measured by a portable EEG headset.
In the authors’ previous studies, principal component analysis extracted
significant features from EEG signals to construct neural network classifiers.
To improve the performance, the authors have implemented a Stacked Autoencoder
(SAE) for the classification. The SAE carries out feature extraction and
classification in a form of multi-layered neural network. Experimental
results showed that the SAE outperformed the previous classifiers.
