In this case, the fuzzy set is =k, {"Very tall", "Somewhat tall", "Moderately tall"}. Each member of the set has a mathematical value that represents the level or degree of membership. In our example, the set can be represented, along with the degree of membership, as {"Extremely tall":1.0, "Very tall":0.8, "Somewhat tall":0.6, "Moderately tall":0.2}. The input can be plotted on a curve that represents the values in the fuzzy set along with the degrees of membership:
Let's define some standard terminology around fuzzy ...
