simGK {ipsfs}

IFS similarity measure simGK

Description

IFS similarity measure values using simGK computation technique with membership, and non-membership values of two objects or set of objects.

Usage

simGK(ma, na, mb, nb, k)

Arguments

ma

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

na

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

mb

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

nb

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

k

A constant value, considered as 1

Value

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