The matrix factorization approach to fuzzy clustering can be looked at from several perspectives. The potential areas of research include among others: new approaches to prototypes, pattern recognition, computer vision, big data, cluster validation indices, estimation algorithms, software tools, and applications to any field of investigation where the fuzzy sets can be relevant. At the present time, we are essentially focusing on new approaches to prototypes, the cluster validation problem and to provide software for practitioners.
