An alive electroencephalogram analysis system to assist the diagnosis of epilepsy [pdf]Paper  abstract   bibtex   
Computer assisted electroencephalograph analysis tools are trained to classify the data based upon the “ground truth” provided by the clinicians. After development and delivery of these systems there is no simple mechanism for these clinicians to improve the system's classification while encountering any false classification by the system. So the improvement process of the system's classification after initial training (during development) can be termed as `dead'. We consider neurologist as the best available benchmark for system's learning. In this article, we propose an `alive' system, capable of improving its performance by taking clinician's feedback into consideration. The system is based on taking DWT transform which has been shown to be very effective for EEG signal analysis. PCA is applied on the statistical features which are extracted from DWT coefficients before classification by an SVM classifier. After corrective marking of few epochs the initial average accuracy of 94.8% raised to 95.12.
