aWe will consider one example of each clustering technique:k-means clustering,and its variants, as an example of partitional clustering, and agglomerative hierarchical clustering as an example of hierarchical clustering. 我们将考虑每个使成群的技术的一个例子:k意味成群和它的变形,为例partitional成群和会...
each represented by a prototype which is the centroid of the objects in a cluster. In such clustering, each data object belongs Fig. 8.5 The result ofk-means clustering on handwritten digits data (The k意味成群是partitional的例子使成群的数据被划分在非重复群之间的地方,是对象矩心在群的原型代表的...

In this research investigation, we first propose a concept of extracting cluster-level uncertainty of any coordinate of a univariate dataset from K-means clustering of the dataset of concern. We also parallelly propose the notions of upper bound uncertainty and lower bound uncertainty to the afore-...
As k-means clustering requires to specify the number of clusters to generate, we’ll use the function clusGap() [cluster package] to computegap statisticsfor estimating the optimal number of clusters . The functionfviz_gap_stat() [factoextra] is used to visualize the gap ...
