The major challenges and future trends of data clustering will also be introduced in this chapter. The remainder of this chapter is organized as follows. The background of data clustering will be introduced in Section 2, including the definition of clustering, categories of clustering techniques, ...
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...

The unlabeled data, instead of being discarded, are also used in the learning process. In semi-supervised clustering, instead of specifying the class labels, pair-wise constraints are specified, which is a weaker way of encoding the prior knowledge. A pair-wise must-link constraint corresponds ...
Clustering has primarily been used as an analytical technique to group unlabeled data for extracting meaningful information. The fact that no clustering algorithm can solve all clustering problems has resulted in the development of several clustering algorithms with diverse applications. We review data clu...
There are many different clustering algorithms. One of the oldest and most widely used is the k-means algorithm. In this article I’ll explain how the k-means algorithm works and present a complete C# demo program. There are many existing standalone data-clustering tools, so why would you ...
The practice of classifying objects according to perceived similarities is the basis for much of science. Organizing data into sensible groupings is one of the most fundamental modes of understanding and learning. As an example, a common scheme of scient
