FuzzyLogic.jl

Julia library for fuzzy logic and applications.

Opportunities

Wide functionality! Mamdani and Sugeno output systems of the 1st and 2nd types are available, several https://lucaferranti.github.io/FuzzyLogic.jl/stable/api/memberships [membership functions] and https://lucaferranti.github.io/FuzzyLogic.jl/stable/api/fis [parameters of algorithms].
Compatibility! Read models from files https://ffll.sourceforge.net/fcl.htm [IEC 61131-7 Fuzzy Control Language], https://en.wikipedia.org/wiki/Fuzzy_markup_language [IEEE 1855-2016 Fuzzy Markup Language] and Matlab Fuzzy toolbox .fis.
Expressiveness! A clear domain-specific language for writing a model in the form of user-friendly Julia code.
Performance! Multiple visualization tools for debugging and customizing the model.
*Portability! Compile the final model into Julia code.

An example of a quick start

fis = @mamfis function tipper(service, food)::tip
    service := begin
      domain = 0:10
      poor = GaussianMF(0.0, 1.5)
      good = GaussianMF(5.0, 1.5)
      excellent = GaussianMF(10.0, 1.5)
    end

    food := begin
      domain = 0:10
      rancid = TrapezoidalMF(-2, 0, 1, 3)
      delicious = TrapezoidalMF(7, 9, 10, 12)
    end

    tip := begin
      domain = 0:30
      cheap = TriangularMF(0, 5, 10)
      average = TriangularMF(10, 15, 20)
      generous = TriangularMF(20, 25, 30)
    end

    service == poor || food == rancid --> tip == cheap
    service == good --> tip == average
    service == excellent || food == delicious --> tip == generous
end

fis(service=1, food=2)
