摘要
针对历史灾害记录的描述性、简约性问题,提出一种基于蚁群聚类的历史灾害分级方法。利用灰色关联分析方法对灾害数据进行归一化处理后,再通过蚁群自动聚类的结果来划分历史灾害的等级,以避免人为的主观任意性干扰。通过与其他分级方法的性能对比,实验结果证明该方法具有较高的精确性和实用性。
Concerning the description and simplicity of historical disaster records,a historical disaster classification method based on ant colony clustering was proposed in this paper.The disaster data were normalized by using gray relational analytical approach,and then the levels of historical disasters were divided by the results of ant colony automatic clustering,so as to avoid the arbitrary man-made interference.In comparison with other classification methods in performance,the experimental results show that this method has higher precision and practicality.
