EEG Channel Selection Using Particle Swarm Optimization for the Classification of Auditory Event-Related Potentials
Figure 6
Illustration of the Pareto front found by the algorithm in each MHPSO case for a representative subject. The vertical and horizontal axes denote the number of selected channels and the average classification accuracy, respectively. The blue dots show the fitness of all the positions visited by the swarm. The red dots represent are the positions that belong to the Pareto front. The first MHPSO case was omitted because the Pareto front in this case is meaningless.
