摘要
本文对用于聚类中心初始化的势函数的几个参数选择问题进行了讨论,给出了这些参数的两种形式。同时提出了一种新的使用密度函数法进行聚类中心初始化的方法,进行了一组对比实验,得到了令人满意的结果。
The problems of parameter selections for potential function used to initialize cluster centers are discussed, and two methods are given for determining these parameters. Then a new density function to initialize cluster centers is also given which is computational effective. Finally, a set of compared experiments is presented to show the effectiveness of the proposed methods.
