Grid-based clustering algorithms divide the data space into a finite number of cells or grid boxes and assign data points to these cells. The resulting grid structure forms the basis for identifying clusters. An example of a grid-based algorithm is STING (Statistical Information Grid). Grid-base...

This is done to partition or segment the database into components that then give the user a more general view of the data. In this case text, we do not differentiate between segmentation and clustering. A simple example of clustering is found in Example 5.1. This example illustrates the ...
In this article, we describe the common distance measures used to compute distance matrix for cluster analysis. We also provide R codes for computing and visualizing distances. Cluster Analysis Example: Quick Start R Code 20 mins Alboukadel Kassambara ...
Exclusive vs. non exclusive clustering In the first case data are grouped in an exclusive way, so that if a certain datum belongs to a definite cluster then it could not be included in another cluster. A simple example of that is shown in the figure below, where the separation of points...
(cluster) of values existing in terrorist event data. For instance, clusters of space–time patterns of terrorist events[142]are used for analysis of terrorist outbreaks. Similarly,social network analysis(SNA) is another example of approaches that utilize clustering to identify criminal groups, ...
The density-based clustering (DBSCAN is a partitioning method that has been introduced in Ester et al. (1996). It can find out clusters of different shapes and sizes from data containing noise and outliers. In this chapter, we’ll describe the DBSCAN algorithm and demonstrate how to compute ...
