simNNNG2: PFS similarity measure simNNNG2

Description

PFS similarity measure values using simNNNG2 computation technique with membership, and non-membership values of two objects or set of objects.

Usage

simNNNG2(ma, na, mb, nb, k)

Arguments

ma

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

na

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

mb

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

nb

PFS 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 PFS similarity values of data set y with data set x
