B. 分组的预测
原标题:Predict in Clustering

In R language is there a predict function in clustering like the way we have in classification? What can we conclude from the clustering graph result that we get from R, other that comparing two clusters?

问题回答

Clustering does not pay attention to prediction capabilities. It just tries to find objects that seem to be related. That is why there is no "predict" function for clustering results.

然而,在许多情况下,基于各组别的学习班子提高了业绩。 为此,你基本上训练班级人员将物体分配给适当的组群,然后使用只受过本组实例培训的班级师进行分类。 如果分组是纯洁的,你甚至可以绕过第二步。

原因如下:可能有多种类型被归类为同一标签。 可能难以对一组完整数据进行训练,因为它将同时努力学习这两个组。 将班级分成两个组,并对每个组别进行单独培训,可大大便利这项工作。

许多包件都提供<条码> 字标/代码>的集束物体方法。 其中一个实例是clue,cl_predict

这样做的最佳做法是适用用于分组培训数据的相同的规则。 例如,在Kernel K-Means,你应当对你的数据点与集群中心之间的距离进行计算。 最低限度确定分组分配(。 例如。 在分门别类时,你应当把数据点与培训数据功能的异同性相比较,比较该空间与K-Means中心之间的电子幻灯距,并至少确定你的分组任务(。 例如
