Cross-validated solutions of PSO–SVM (in blue) and HHPSO–SVM (in red) from Stage I, where x-axis represents the number of selected voxels and y-axis represents the classification error. Lighter color means that the solution is obtained in earlier optimization iterations, while darker color denotes the solution is obtained in later optimization iterations. (Color figure online)
