Web从 Kmeans 聚类算法的原理可知， Kmeans 在正式聚类之前首先需要完成的就是初始化 k 个簇中心。同时，也正是因为这个原因，使得 Kmeans 聚类算法存在着一个巨大的缺陷——收敛情况严重依赖于簇中心的初始化状况。试想一下，如果在初始化过程中很不巧的将 k 个（或大多数）簇中心都初始化了到同一个簇中，那么在这种情况下 Kmeans 聚类算法很大程度 … WebThat paper is also my source for the BIC formulas. I have 2 problems with this: Notation: n i = number of elements in cluster i.
