In data mining, various methods of clustering algorithms are used to group data objects based on their similarities or dissimilarities. These algorithms can be broadly classified into several types, each with its own characteristics and underlying principles. Let’s explore some of the commonly used ...
2022 Little Lion ScientificThe paper discusses aspects of data research, in-depth data analysis, knowledge acquisition, methods of data processing in the knowledge base, methods of intellectual analysis, and application of data mining in the field of medicine. A group of HIV-infected patients was ...
Clustering and Association Rule Mining are two of the most frequently used Data Mining technique for various functional needs, especially in Marketing, Merchandising, and Campaign efforts. Clustering helps find natural and inherent structures amongst the objects, where as Association Rule is a very powe...

Data clusteringconsists of data mining methods for identifying groups of similar objects in a multivariate data sets collected from fields such as marketing, bio-medical and geo-spatial. Similarity between observations (or individuals) is defined using some inter-observation distance measures including Eu...
For a mixed data, you can, first, compute a distance matrix between variables using the daisy() R function [in cluster package]. Next, you can apply hierarchical clustering on the computed distance matrix. For example: library(cluster) library(factoextra) # Load data data(flower) head(flowe...
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...

A simple example of clustering is found in Example 5.1. This example illustrates the fact that that determining how to do the clustering is not straightforward. As illustrated in Figure 5.1, a given set of data may be clustered on different attributes. Here a group of homes in a geographic ...
As discussed earlier, various cluster methods have been created to group the data. \(K\)-means is an example of a partitioning clustering algorithm because it operates based on the cluster centroid15,19. Numerous uses of the \(K\)-means cluster have been documented. In addition to enhancing...
