simSGFDK1: SFS similarity measure simSGFDK1

Description

SFS similarity measure values using simSGFDK1 computation technique with membership,non-membership, and indeterminacy membership values of two objects or set of objects.

Usage

simSGFDK1(ma, na, mb, nb, ia, ib, k)

Arguments

ma

SFS membership values for the data set x computed using either triangular or trapezoidal or guassian membership function

na

SFS non-membership values for the data set x computed using either Sugeno and Terano's or Yager's non-membership function

mb

SFS membership values for the data set y computed using either triangular or trapezoidal or guassian membership function

nb

SFS non-membership values for the data set y computed using either Sugeno and Terano's or Yager's non-membership function

ia

SFS indeterminacy membership values for the data set x

ib

SFS indeterminacy membership values for the data set y

k

A constant value, considered as 1

Value

The SFS similarity values of data set y with data set x
