Description

PtLess is a set of programs to do prototype-less fuzzy clustering, that is, the clustering result is described only by a fuzzy partition matrix, but there are no prototypes to describe the clusters. For GNU/Linux there is also a viewer that visualizes the clustering result.

If you have trouble executing the programs on Microsoft Windows, check whether you have the Microsoft Visual C++ Redistributable for Visual Studio 2017 (see under "Other Tools and Frameworks") installed, as the programs were compiled with Microsoft Visual Studio 2017.

A description of the ideas underlying this approach can be found in the following papers:
