... Given a set of unit, a cluster is the maximal of connected dense units. Two points are in the same cluster if the units they belong to are connected or there exist a set of dense units that are each other connected. Problem Statement: Given a set of data points D, desired number of intervals σ on ea ...

Nearest-neighbor chain algorithm

In the theory of cluster analysis, the nearest-neighbor chain algorithm is a method that can be used to perform several types of agglomerative hierarchical clustering, using an amount of memory that is linear in the number of points to be clustered and an amount of time linear in the number of distinct distances between pairs of points. The main idea of the algorithm is to find pairs of clusters to merge by following paths in the nearest neighbor graph of the clusters until the paths terminate in pairs of mutual nearest neighbors. The algorithm was developed and implemented in 1982 by J. P. Benzécri and J. Juan, based on earlier methods that constructed hierarchical clusterings using mutual nearest neighbor pairs without taking advantage of nearest neighbor chains.
