[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
For this purpose, we discuss the use of Agglomerative Hierarchical Clustering (AHC) on eU, K and eTh airborne gamma-ray spectrometry grids. The AHC process allows primarily to segment the geophysical maps into zones having coherent U, K and Th contents. The analysis of these contents are ...
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...

AMVIDC is a data clustering algorithm based on agglomerative hierarchical clustering (AHC) which uses minimum volume increase (MVI) and minimum direction change (MDC) as clustering criteria. The algorithm is presented in detail in the following publication:...

However, to the best of our knowledge, how to reduce the density bias in hierarchical clustering using data-dependent kernels is yet to be explored. Here, we contend that the same root cause yields the bias in T-AHC. We then provide the formal analysis and explanation as to why a well-...

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 ...
