simL: IFS similarity measure simL

Description

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

Usage

simL(ma, na, mb, nb, ha, hb, p, 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

ha

IFS hesitancy values for the data set x

hb

IFS hesitancy values for the data set y

p

Lp norm values for measuring the p-norm distance between x and y, values range from 1 to 5

k

A constant value, considered as 1

Value

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