数据挖掘在三维堆芯仿真中的应用
pplication of data mining in the simulation of three-dimensional core
数据挖掘是在大量数据中,发现有用的、人们感兴趣的信息的过程。支持向量回归机(SVR)是一种新的数据挖掘算法,该算法是支持向量机(SVM)在回归估计中的应用。本文基于三维堆芯仿真程序之上,通过运行三维堆芯仿真程序得到堆芯功率随时间变化的数据,然后分别利用SVR算法和传统方法对数据进行处理,并得到各自相应的堆芯功率分布曲线。通过比较结果,SVR具有无事先人为强加性,直接由数据内在关系拟合而成,得到的结果更准确,可以用在其他核工程的数据处理中。
ata mining is the process in which useful and interesting information are found. Support vector machine for regression (SVR) is a new data mining algorithms, which is the application of support vector machine (SVM) to regression estimation. This paper is based on the three-dimensional core simulation program and the simulation data of core power changes are obtained by running this program. Then these data are processed by SVR algorithm and traditional method, respectively and the corresponding core power distribution curves are obtained. By comparing the results, it is found that SVR do not require a prior knowledge such as parametric trends of data and is dependent on the intrinsic relationship of data directly. Thus, the results handled by SVR are more accurate than those by traditional method and it is suitable for other data processing.
