Density-based cluster analysis, Ftransformation, fuzzy approximation, DBSCAN.

In this contribution we provide an application of the technique of F-transform. We demonstrate that by using a simple density-based preprocessing, the applicability of F-transform in data analysis can be significantly improved. Despite of the fact that our procedure is demonstrated by a well-known DBSCAN algorithm and the technique of F transform, the ideas are general enough to be applied for other density-based clustering algorithms and regression techniques, respectively.
