Hedge

Hedge

Bases: ABC

Abstract class for hedges.

Hedges are used in the antecedent and consequent of a rule to modify the membership function of the term it precedes.

The hedges in the library can be ordered based on the difference between the membership function \(\mu(x)\) and its hedge \(h(\mu(x))\) as follows (from most similar to least): Seldom \(<\) Somewhat \(<\) Very \(<\) Extremely \(<\) Not \(<\) Any
