Query: Canonical PSO Based k-Means Clustering Approach for Real Datasets   "Clustering" the significance and application of this technique is spread
over various fields. Clustering is an unsupervised process in data mining, that
is why the proper evaluation of the results and measuring the compactness and
separability of the clusters are important issues.The procedure of evaluating
the results of a clustering algorithm is known as cluster validity measure.
Different types of indexes are used to solve different types of problems and
indices selection depends on the kind of available data.This paper first
proposes Canonical PSO based K-means clustering algorithm and also analyses
some important clustering indices (intercluster, intracluster) and then
evaluates the effects of those indices on real-time air pollution
database,wholesale customer, wine, and vehicle datasets using typical K-means,
Canonical PSO based K-means, simple PSO based K-means,DBSCAN, and Hierarchical
clustering algorithms.This paper also describes the nature of the clusters and
finally compares the performances of these clustering algorithms according to
the validity assessment. It also defines which algorithm will be more desirable
among all these algorithms to make proper compact clusters on this particular
real life datasets. It actually deals with the behaviour of these clustering
algorithms with respect to validation indexes and represents their results of
evaluation in terms of mathematical and graphical forms.
