“…On the other hand, as the electronic healthcare dataset overgrows, fuzzy techniques and fuzzy inference systems (FIS) are becoming more common for accurate and early diagnosis of common diseases in patients. For instance, some of the new proposed intelligent models can be introduced as Fuzzy inference system [5,6,7], Adaptive neuro-fuzzy inference system [8,9], Knowledge graph [10], Fuzzy knowledge graph (FKG) [11,14,21], Mamdani Complex fuzzy inference system (M-CFIS) [12,13], and so on. However, existing intelligent techniques used in these new methods have limitations when applied in decision-making support systems with limited input data.…”
