Fuzzy relational compositions, Excluding features, Fuzzy quantifiers, Classification, Odonata

Fuzzy relational compositions play a crucial role in fundamentals of fuzzy mathematics as well as in distinct application areas. Recent studies introduce distinct generalizations, e.g., incorporation ofexcluding features or the use of generalized quantifiers. No matter the huge positive potential of these approaches, we demonstrate on areal example, that some limitations even for these extensions may be encountered if the features are constructed in a certain specific yet very natural way and then, further improvement may be obtained,if a sort of grouping of features is applied. Then, working on the partitioned universe of features, the combination of both above mentioned extensions will be introduced and experimentally validated.
