On the classification of single evoked potentials using a quadratic classifier

It has been shown that using a computationally simple technique it is possible to classify single event-related potentials associated with upper and lower visual field stimulation with a high degree of accuracy. A flow chart of the algorithm and the FORTRAN 77 computer program required to perform the classification just described are included in the Appendix. The program as given in the Appendix is for a 2 class problem only. Memory limitations (33000 bytes 16-bit words) per user in the time-shared system utilized limits the amount of data that may be in core at any one time. A 2 class, 5 step problem takes approximately 5 min in a PDP ll/45 System (Digital Equipment Corp.).
