摘要
投影寻踪模型是一种新兴的、能够有效处理高维、复杂非线性数据的技术方法。在水文水资源系统分析中,常受到复杂高维问题的困扰,投影寻踪模型的引入使这一问题得到了很好的解决。在阐述了投影寻踪模型的特点、研究内容及存在问题的基础上,着重论述了两类主要的投影寻踪模型及其在水文水资源系统分析中的应用,并且举一应用实例进一步说明该模型的具体使用方法。希望能使不同领域的研究者了解投影寻踪模型,并引起关注;也希望通过大家的努力使该模型不断地完善。
Projection pursuit model is a newly arisen data processing technique which is special in processing high dimensional and complicated nonlinear data. Hydrology and water resources system analysis was always puzzled by complicated high dimensional problem, so conducting projection pursuit model could solve the problem commendably. On the basis of expatiating on the main characteristics, research content and existing problems of projection pursuit model, we put the important discuss on the two main types of pro jection pursuit model and their applications in hydrology and water resources system analysis, and gave an example to illuminate the practical using method of the model further. We hope the paper can make researchers in various fields know and pay attention to projection pursuit model, and improve it.
