The data clustered sets have become a challenging issue ...utility, cluster analysis has long been used in a wide variety of fields: psychology and other social sciences, biology, statistics, pattern recognition, information retrieval, machine learning, and data mining. In this chapter we provide a short introduction to cluster analysis, and then focus on the challenge of clustering high dimensional data.Abstract. Following Henry Small in his approach to cocitation analysis, highly cited sources are seen as concept symbols of research fronts. But instead of cocited sources, I cluster citation links, which are the thematically least heterogenous elements in bibliometric studies. To obtain clusters representing topics characterized by concepts, I restrict link clustering to citation links to ...

In a recent paper, we found that PCA is able to compress the Euclidean distance of intra-cluster pairs while preserving Euclidean distance of inter-cluster pairs. Notice that K-means aims to minimize Euclidean distance to the centers. Hence the compressibility of PCA helps a lot.For instance, the papers [34], [35] conducted flight trajectory clustering tasks with a focus on airspace protection and aircraft conflict detection. Andrew Churchill and Michael Bloem [36] proposed a hierarchical clustering method for clustering aircraft taxi trajectories to ultimately identify anomalous trajectories.Clustering Algorithms Explained.
