Depth-bounded fuzzy simulations and bisimulations between fuzzy automata
2023, Fuzzy Sets and SystemsCharacterization and computation of approximate bisimulations for fuzzy automata
2022, Fuzzy Sets and SystemsCitation Excerpt :Uniform fuzzy relations were originally intended to serve as fuzzy functions which provide a correspondence between fuzzy functions and fuzzy equivalence relations, analogous to the correspondence between crisp functions and crisp equivalence relations (cf. [10]), but they have been applied in many different situations, to systems of fuzzy relation equations, fuzzy homomorphisms and fuzzy relational morphisms of algebras, bisimulations for fuzzy automata, fuzzy social network analysis, etc. (cf. [10,12,29–31]; see also [14,15]). It is worth noting that fuzzy automata have a long history of applications in various fields, including control engineering, decision-making, robot control, clinical monitoring, pattern analysis, image processing, and artificial intelligence (see, e.g., [1,4,56,62,64,71]). In all such applications where we use a fuzzy automaton as a model of an observed system, it is very convenient to use a simpler fuzzy automaton, even at a cost that the new fuzzy automaton is not strictly language equivalent to the original one, but has slightly different behaviour.
Further improvements of determinization methods for fuzzy finite automata
2016, Fuzzy Sets and SystemsCitation Excerpt :Fuzzy automata originated in the late 1960s as a model of computation that combines the capabilities of classical automata and fuzzy logic and is able to handle the uncertainty which is inherent in many applications. Over the years they have gained significant applications in many areas such as approximate string matching and searching, neural networks and neuro-fuzzy systems, fuzzy signal processing, and clinical monitoring, to name but a few [5,22,47,55,58,61,65]. In recent years, fuzzy automata were also used as the basic model for fuzzy discrete-event systems, which have been successfully applied to biomedical control for HIV/AIDS treatment planning, robotic control, intelligent vehicle control, waste-water treatment, examination of chemical reactions, fault diagnosis, and in other fields [6–8,14,21,39–43,54,56,59,68].
