DrasticSum

DrasticSum ¶

Bases: SNorm

SNorm to compute the drastic sum of any two values.

Equation

\(a \oplus b=\begin{cases} \max(a,b) & \mbox{if } \min(a,b)=0 \cr 1 & \mbox{otherwise} \end{cases}\)

compute(a: Scalar, b: Scalar) -> Scalar

Compute the drastic sum of two membership function values.

Parameters:

Name	Type	Description	Default
`a`	`Scalar`	membership function value	required
`b`	`Scalar`	membership function value	required

Returns:

Type	Description
`Scalar`	\(a \oplus b=\begin{cases} \max(a,b) & \mbox{if } \min(a,b)=0 \cr 1 & \mbox{otherwise} \end{cases}\)
