GINKGO, a program for non-standard multivariate fuzzy analysis
Miquel De Cáceres, Xavier Font, Francesc Oliva, Sergi Vives · 2006
Many multivariate programs are expensive commercial packages or require expensive third party software. Other applications are freely available to academic researchers but are limited to one operating system. This paper presents GINKGO, a free easy-to-use multi-platform Java application mainly oriented towards to non-standard classification analysis. This orientation is pursued (1) by providing users with several similarity and dissimilarity measures, (2) by allowing the execution of several crisp or fuzzy prototype-based clustering methods on arbitrary distance matrices, and (3) by including standard and non-standard facilities for evaluating the quality of clusters. Along with the software presentation, two methodological improvements are also given, which are available in the program. First, the implementation of a new
