Abstract :
What´s in a name? Over the last several years, Lotfi Zadeh has been using the definition of a cluster as an example of a very common fuzzy term that we humans use without a real definition. This paper represents an attempt to construct a degree of clusterness for a given set of points. We introduce two approaches, one based on the Possibilistic C-Means and the other on a Visual Assessment of Cluster Tendency. We compare the measures on several synthetic data sets and discuss the results.
