Agglomerative Hierarchical Clustering 这里的AHC和线差不多,只是在处理图时,不用双向链表了。为有效找到最小MSE的node,建最小堆数据结构。具体merge操作和前面一致。 图G由node集合 V和相邻关系边集合E组成。先用V去建最小堆。找到最小MSE对应的node v。从E中找v邻域u,先尝试merge计算MSE,找最小的。如果最后...

[164]proposed a method for estimating the optimal number of clusters using an agglomerativehierarchical clustering(AHC) approach with a single linkage. The estimation is performed after analyzing the clustering effect on the dataset and applying a proposed a clustering validity index. The validity ...

This paper presents a agglomerative hierarchical clustering-based (AHC) algorithm to effectively analyze and categorize charging station load profiles. First, a substantial dataset of multiple charging stations is preprocessed and normalized to address the problem of varying load scales across different ...
This paper presents new clustering algorithms which are based on agglomerative hierarchical clustering (AHC) with centroid method. The algorithms can handle with data with tolerance of which the concept includes some errors, ranges, or missing values in data. First, the tolerance is in- troduced ...
By applying this approach and defining a set performance target, this study proposes a makeshift decision framework that integrates a data mining procedure (agglomerative hierarchical clustering (AHC)) into the decision-making process to provide a simplified 3E assessment of building retrofits on a ...
