Detection and Estimation of Single Event Related Potentials.
Abstract
The Performance of linear stepwise discriminant analysis and quadratic discriminant functions in classifying single event related brain potential are compared. A frequent V and infrequent inverted V visual stimulus was employed and measurements were made with scalp electrodes at Pz, Cz, and Oz. Results are reported for using training data from one test to classify results of that test, to classify data from a test at a different time, and for classifying data from other subjects. Performance using the quadratic discriminant function was generally superior to that of the linear discriminant function. Single event classification accuracies greater than 90% were obtained when training and test data from the same experiment were used. Substantially poorer performance was obtained when data from one test was used to classify responses measured from a test conducted at a different time or using a different subject. Reasons for these discrepancies are discussed. (Author)
