摘要
针对传统灰色定权聚类方法中权重是事先给定的,不具有客观性的问题。借鉴传统的shannon信息熵的思想,本文提出了基于Reny熵权确定权重的方法。构造了基于构造了基于Reny熵权的灰色定权聚类评估方法的算法。该方法利用系统状态数据为依据,通过计算熵来得到决策权重,以实际问题为背景进行了算例实证研究。结果表明该方法计算简单,权重确定客观,对灰色聚类决策理论进行了补充和完善。
On account of the weight of traditional grey fixed weight clustering methords which is given in advance and does not have objective problems,the passage proves out a method of decicling weight that based on Reny entropy,owing to the thinking of traditional Shannon entropy of information,and construct methods that based on Reny entropy.The algorithem makes use of system state data,throughing calculating entropy to have decision weight,and makes example stheric syndrome research on the background of practical problem.The result proves that the method is easy in calculating and the weight decision is objective,and also complement and perfect grey clustering decision theory.
