Abstract:

In order to resolve the problem of optimizing RBF, an elitist model-immune genetic algorithm is put forward to optimize the structure and parameters of the RBF neural network. The model uses elite selection strategy and adds the factor of simulated annealing. It ensures good genes to be retained into the next generation. At the same time, it increases the diversity of variation to a certain extent through the disturbance of the annealing factor. And the model improves the convergence rate and local search capacity of the whole algorithm. Experimental results are used to demonstrate the effectiveness and reliability of the algorithm when predicting the situation of network information content security incidents.
