WCluster is a java program designed to perform hierarchical clustering. Whereas most hierarchical clustering software only allows users to assign weights to either rows or columns, WCluster lets you assign weights to individual data points. For example, this can be very useful if a particular row...

As recently published in Science (see reference)Simple and effective means of clustering any data for which a similarity matrix can be constructed. Does not require similarity matrix meet the standards for a metric. The algorithm applies in cases where the similarity matrix is not symmetric (the...

Generic clustering/load-balancing platform (over a LAN or internet) using java based P2P Aorta workers that execute java 'tasklets'. Various tasklets can be implemented to solve fractals, process images, render webpages, crack RSA 'brute force'.

Many ant species exhibit the behavior of clustering corpses to form cemeteries. Each ant seems to behave individually, moving randomly in space while picking up or depositing (dropping) corpses. The decision to pick up or drop a corpse is based on local information of the antd-deOaos current...

This is a tool for K-means clustering. After trying several different ways to program, I got the conclusion that using simple loops to perform distance calculation and comparison is most efficient and accurate because of the JIT acceleration in MATLAB.The code is very simple and well documented,...

(SE) is developed to estimate the number of clusters (NC) for PAM clustering algorithm. By inspecting whether it is stable that two potential clusters are separated or merged, SE focuses on the separability of two closest clusters among k potential clusters (called twin-clusters) when a data set...

The statistics toolbox contains routines for hierarchical clustering, including the cluster routine uses the SAHN tree to group data into clusters. However, the toolbox seems to lack a routine that uses the SAHN tree to describe the hierarchical relationship between those clusters. This routine...
