Defuzzification SOM, MOM, LOM for trapezoids
Trapezoids are automatically transformed to singletons.
The output value is then computed in the same way as for singletons.
Recommendation
• Use singletons to have easier insight to the output inference
mechanism
• No functionality is lost
Output = term with maximal DOF = zero
Output = Default Value, if all DOFs = 0
DOF(zero) is maximal
