基于免疫遗传算法的洪灾神经网络评估模型
Immune genetic algorithm based neural network model for flood disaster evaluation
【摘要】 灾情评估的结果既是制定防洪减灾决策的基本依据,也是评价防洪工作成效的重要指标。提出了一种基于免疫遗传算法优化的神经网络模型(IGA-NN)并用于洪水灾情的评估,给出了IGA-NN的设计方法和优化步骤。同时还将IGA-NN与标准遗传算法优化的神经网络模型进行了比较,显示了IGA-NN的优越性。最后通过实例,验证了IGA-NN的实用性。
【Abstract】 The result of disaster evaluation is not only the basis for decision-making to flood control but also the important index of judging flood control effect.In this paper,an immune genetic algorithm based on neural network model(IGA-NN) for flood disaster evaluation is proposed.The design method and optimization procedures of the IGA-NN is provided.Also,this paper demonstrates superiority of the IGA-NN by comparing it with the neural network optimized by standard genetic algorithm.Finally,the practicality of the IGA-NN is verified by practical application.
