The comparative study on agglomerative hierarchical clustering using numerical data

Abstract

In theconventional way of convert data into a singleton or merging has many drawbacks mainly computational complexity. In this context hierarchical clustering method for quantitative measures of similarity among objects that could keep not only the structure of categorical attributes but also relative distance of numeric values. For numeric data the number of clusters can be validated through integral data, the hierarchical and partitioning methods the relationships among categorical items. In This Paper we hereinvestigate linkage criterions in hierarchical clustering algorithm performance calculations using with Euclidian distance measure and some clustering techniques and their applications have been discussed. It also describes the necessities to be calculated for constructing a well-organized to handle the huge data sets. As the study initially investigates distinct issues for creating clusters with numeric attributes. The efficiency is obtained by clustering of datasets that comprises of numeric attributes related to distinct applications. Significant issues such merging object naturally uses Euclidean distance is resolved by using Agglomerative methods.

Livestock Disease Data Management for E-Surveillance and Disease Mapping Using Cluster Analysis

“…Hierarchical clustering can be either agglomerative (bottom-up), where smaller clusters are merged into larger clusters, or divisive (top-down), where larger clusters are split into smaller clusters it uses different linkage methods to measure the distance between two sub-clusters of data points. The most common linkage types are: Single, Complete and Average [34].…”

UR: SMART–A tool for analyzing social media content

“…In contrast to classification, clustering describes unsupervised analysis approaches, which focus on the assembly process of data to achieve automatically defined homogenous groups by identifying statistical structures and patterns (Dayan 1999;Ahuja and Dubey 2017). Clustering approaches like k-means (MacQueen 1967; Orkphol and Yang 2019), expectation maximization (Dempster et al 1977;Shelke et al 2017) and agglomerative hierarchical clustering (Tan et al 2005;Praveen et al 2020) renounce a reduction of dimensionality and try to group matching elements of the dataset based on their structure (Feldman and Sanger 2007;Heyer et al 2006;AL-Sharuee et al 2018). The resulting clusters are derived directly from the structure of the data themselves (Feldman and Sanger 2007;Heyer et al 2006).…”
