核主成分分析的参数优化及其在水资源可持续利用综合评价中的应用
Parameters optimization of kernel principal component analysis and its application in evaluation of water resources sustainable utilization
【摘要】 针对核主成分方法应用时核函数参数确定困难,提出建立基于贡献率的优化问题,并用实码加速遗传算法对其实施优化求解,客观地确定了各参数的值,并将该核主成分方法应用于水资源可持续利用综合评价问题中,取得了良好的效果。
【Abstract】 According to the choice of kernel function parameters in the kernel principal component method,an optimization question based on the contribution rate is established.The real coded accelerating genetic algorithm is used to find an optimization solution.The values of the parameters are determined objectively.The kernel principal component method was used to evaluate and analyze water resources sustainable utilization,and a satisfactory result was obtained.
