Fuzzy hierarchical characteristics clustering FHiChC

In order to identify which properties (variables) are responsible for the observed similarities and dissimilarities between the chemical elements, we also applied a very interesting algorithm, namely, fuzzy hierarchical crossclassification (FHiCC). The technique produces not only a fuzzy partitioning of the chemical elements but also a fuzzy partitioning of the physical and chemical properties considered. Moreover, the fuzzy hierarchical characteristics clustering (FHiChC) and fuzzy horizontal characteristics clustering (FHoChC) procedures showed very high similarities between the chemical and structural... 

In order to develop the classifications presented in this section, we will apply the fuzzy divisive hierarchical clustering (FDHiC) procedure described in the theoretical section to different characteristic sets considered here. The hierarchical procedure obtained in this way is called fuzzy hierarchical characteristics clustering (FHiChC).
