摘要: The high dimensional nature of EEG data due to large electrode numbers and long task periods is one the main challenges studying EEG. Evolutionary alternatives conventional dimension reduction methods exhibit advantage not requiring entire recording sessions for operation. Particle Swarm Optimization (PSO) an method that achieves performance through evaluation several generations possible solutions. This study investigates feasibility a 2 layer PSO structure synchronous both period dimensions using 4 motor imagery data. results indicate potential proposed paradigm with insignificant losses in classification practical uses subject transfer applications.
