p-中位数聚类模型代表了一种将数据集划分为不相交的非分层组的组合方法。对象类是围绕范例(数据集中的显示对象)构建的,其余的实例被分配到离它们最近的集群中心。在流行的社会和行为科学统计软件包中,有效的、最先进的p-median聚类实现实际上是不可用的。我们提出了p-中位数聚类,包括对其机制的详细描述,对可用软件程序及其功能的讨论。应用于一个复杂的结构化数据集对食物项目的感知说明p-中位数聚类。
The p-median clustering model represents a combinatorial approach to partition data sets into disjoint, non-hierarchical groups. Object classes are constructed around exemplars, manifest objects in the data set, with the remaining instances assigned to their closest cluster centers. Effective, state-of-the-art implementations of p-median clustering are virtually unavailable in the popular social and behavioral science statistical software packages. We present p-median clustering, including a detailed description of its mechanics, a discussion of available software programs and their capabilities. Application to a complex structured data set on the perception of food items illustrate p-median clustering.
