“…The fuzzy rules, the linguistic values, the fuzzy sets and the shape of the membership functions are usually defined by the modeller, according to the available knowledge about the system to be described, unless a data-driven approach is exploited [ 39 ]. Fuzzy set theory and fuzzy logic found applications across several scientific and engineering disciplines, and FIS allowed fuzzy logic to be effectively adopted in several contexts, both in knowledge-based or data-driven applications, to support decision-making [ 40 , 41 ], meta-heuristics [ 42 ], modelling and control [ 43 , 44 ], clustering [ 45 ], classification tasks [ 46 ] and regression problems [ 47 ].…”
