When Multi-objective Particle Swarm Optimization (MOPSO) optimizes the multi-objective problems of the multiobjective simultaneous learning framework (MSCC)
there are only a few nondominated solutions in MOPSO population.In this case
NSGA-II can keep a lot of good dominated solutions in the population
which will help the population optimize
so this paper brought in NSGA-II as the optimization algorithm.The results of experiments show that
under the optimization of NSGA-II
MSCC framework can get better multi-class classifiers.However
dominated solutions can get better classifiers than nondominated solutions.By observing the changing curves of the maximum classification accuracy rate following with the optimization of populations
this paper found that
when dealing with most of the data sets
the maximum accuracy is not improved following the optimization of populations.
