In this paper we present A-BIRCH, an approach for automatic threshold estimation for the BIRCH clustering algorithm. This approach computes the optimal threshold parameter of BIRCH from the data, such that BIRCH
BIRCH算法全称如下 Balanced Iterative Reducing and Clustering Using Hierarchies 属于树状结构的层次聚类算法的一种,其树状结构的构建是自上而下的,也就是说我们只需要扫描一遍数据,就可以得到树状结构了,因此该算法的运行速度很快。 要理解该算法的运行过程,需要理解以下两个基本概念 1. Cluster Feature 简称CF, 每个...

BIRCH(Balanced Iterative Reducing and Clustering using Hierarchies)是一种用于大规模数据集上的层次聚类算法。该算法于1996年首次提出,目的是在不牺牲聚类质量的前提下,减少大数据聚类问题的计算复杂性。 BIRCH算法的主要优点是其可以处理大规模的数据集,并且仅需要一次或少数几次的数据扫描。该算法通过引入一种特殊的...

Detail: The B I R C H algorithm is a clustering algorithm suitable for large-scale datasets. It constructs a clustering feature feature (c F) tree by setting a uniform threshold for all leaf nodes, and uses different thresholds at each stage to reconstruct the tree. However, it does not ...
multi-dimensional metric data points in an effort to generate the best quality clustering for a given set of resources (memory and time constraints). In most cases, Birch only requires a single scan of the database. In addition, Birch is accepted as the, "first clustering algorithm proposed ...
