#mu(value) ⇒ Object

mu (named for the symbol) is the ‘membership function’, sometimes known as the ‘degree of fit’ or the ‘degree of membership’. This computed value informs HOW MUCH this set activates or fires for the provided input value. A DoM of zero means that this set fits the input not at all; a DoM of 1.0 means that this set fires / fits completely.

  • Args :

    • value -> the input value in question

  • Returns :

    • a ‘fitness’ degree between 0 and 1.0
