Functions

defuzzify

defuzzify(term: Term, minimum: float, maximum: float) -> Scalar

Compute the centroid of a fuzzy set.

The defuzzification process integrates over the fuzzy set using the given range. The integration algorithm is the midpoint rectangle method (https://en.wikipedia.org/wiki/Rectangle_method).

Parameters:

Name	Type	Description	Default
term	Term	fuzzy set to defuzzify	required
minimum	float	value to start defuzzification	required
maximum	float	value to end defuzzification	required

Returns:

Type	Description
Scalar	\(x\)-coordinate of the centroid of the fuzzy set
