A BMI can provide a digital channel for communication in the absence of the biological channels and are used to rehabilitate patients with neurodegenerative diseases, a condition in which all motor movements are impaired including speech leaving the patients totally locked-in. BMI are designed using the electrical activity of the brain detected by scalp EEG electrodes. In this paper five different mental tasks from two subjects were studied, combinations of two tasks are used in the classification process. A novel functional link neural network trained by a PSO algorithm is proposed for classification of the EEG signals. Principal component analysis features are used in the training and testing of the neural network. The average classification accuracies were observed to vary from 80.25% to 93% for the 10 different task combinations for each of the subjects. The proposed network has an average training time of 0.16 sec. The results obtained validate the performance of the proposed algorithm for mental task classification. 2009-12-09T07:32:44Z 2009-12-09T07:32:44Z 2008-08-26 Working Paper vol.3, p.1-6 978-1-4244-2327-9 http://ieeexplore.ieee.org/search/wrapper.jsp?arnumber=4631976 http://hdl.handle.net/123456789/7383 en Proceedings of the International Symposium on Information Technology (ITSim 08) Institute of Electrical and Electronics Engineering (IEEE) |
