Abstract EN
We study the use of nonparametric multicompare statistical tests on the performance of simulated annealing (SA), genetic algorithm (GA), particle swarm optimization (PSO), and differential evolution (DE), when used for electroencephalographic (EEG) source localization.
Such task can be posed as an optimization problem for which the referred metaheuristic methods are well suited.
Hence, we evaluate the localization’s performance in terms of metaheuristics’ operational parameters and for a fixed number of evaluations of the objective function.
In this way, we are able to link the efficiency of the metaheuristics with a common measure of computational cost.
Our results did not show significant differences in the metaheuristics’ performance for the case of single source localization.
In case of localizing two correlated sources, we found that PSO (ring and tree topologies) and DE performed the worst, then they should not be considered in large-scale EEG source localization problems.
Overall, the multicompare tests allowed to demonstrate the little effect that the selection of a particular metaheuristic and the variations in their operational parameters have in this optimization problem.
