Definition Clustering can be considered the most important unsupervised learning technique; so, as every other problem of this kind, it deals with finding a structure in a collection of unlabeled data. Clustering is “the process of organizing objects into groups whose members are similar in some ...
Introduction : Clustering in data mining is a discovery process that groups a set of data The applications of clustering include : categorization of documents on the World Wide Web grouping of genes and proteins that have similar functionality characterization of different customer groups Clustering algo...
