Cluster is a set of programs to do probabilistic clustering (expectation maximization algorithm to find a mixture of Gaussians) and fuzzy clustering (fuzzy c-means algorithm, Gustafson-Kessel algorithm, and Gath-Geva / FMLE algorithm) and to execute the induced set of clusters on new data. The programs are highly parameterizable, so that a large variety of clustering approaches can be carried out. Since version 2.4 the program also contains a competitive learning / learning vector quantization mode, which will eventually supersede the learning vector quantization programs. A brief description of how to apply these programs can be found in the file cluster/ex/readme in the source package.

If you have trouble executing the programs on Microsoft Windows, check whether you have the Microsoft Visual C++ Redistributable Packages for Visual Studio 2015 installed, as the library was compiled with Microsoft Visual Studio 2015.

An extensive treatment of the clustering approaches supported by the programs can be found in my habilitation thesis:
