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 ...

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...
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 ...
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...
17.2Technique used in data mining 17.2.1Clustering Clustering is the task of dividing the population or data points into a number of groups such that data points in the same groups are more similar to other data points in the same group than those in other groups. In simple words, the aim...
If you rearrange your data, it’s very possible that you’ll get a different solution every time you change the ordering of your data. Possible solutions to these weaknesses, include: Solution to issue 1: Compute k-means for a range of k values, for example by varying k between 2 and ...
As science and technology progress and develop rapidly in this day and age, various industry applications have changed the data in a new way, and the explosive growth of data has made traditional data mining unable to perform the current data mining work. The aim of this paper is to study ...
