摘要
首先详细讨论了PAM算法,包括:PAM算法的基本思想,如何替换中心点增进聚类质量,PAM算法的处理流程,代价函数的计算,相异度的计算,复杂度分析等,然后给出了一个实现PAM算法的实例。
Firstly PAM algorithm is discussed in detail,including:PAM algorithm's fundamental idea,how to replace medoids in order to improve the quality of a cluster,PAM algorithm's processing flow,how to compute cost function,how to compute dissimilarity, complexity analysis,and so on.Then an instance of implementation of PAM algorithm is demonstrated.
