- Abstract:
-
Combining the fuzzy rough set theory with the related knowledge on hypernetworks, this paper proposes a fuzzy hypernetwork mode. In comparison with the traditional hypernetwork model, the fuzzy hypernetwork model uses the fuzzy equivalence relationship to replace the distinct equivalence relation in hypernetworks and then improves the generation and evolution of hyperedges on this basis. First, the samples are divided into three regions according to their distribution:positive, boundary, and negative regions. The samples of different regions generate hyperedges in different ways. Second, the hyperedges are also divided into three regions according to their classification results, and the corresponding replacement of hyperedges in different regions is implemented. The experimental results show that the fuzzy hypernetwork classification algorithm presents prominent advantages in terms of accuracy, precision, and recall, thus proving the validity of the classification algorithm.
