Paper Title
Classification of EEG Signals Using Fuzzy Dempster Shafer Classifier
Abstract
ABrain computer interface (BCI) is a communication system, which translates brain activity into
commands for a computer or other devices. Nearly all BCIs contain as a core component a classification
algorithm, which is employed to discriminate different brain activities using previously recorded examples of
brain activity. In this paper, we study the classification accuracy achievable with a Fuzzing method based on
Dempster-Shafer theory. To extract features from the electroencephalogram (EEG), autoregressive (AR) models
and wavelet decomposition are used. To test the classification method an EEG dataset containing signals
recorded during the performance of five different mental tasks is used. We show that the Fuzzy Dempster Shafer
Classifier achieves a higher correct classification rate than the classical voting KNN classifier and the distanceweighted
KNN classifier.
