allindexes: Compute all of the internal indexes

In zcebeci/fcvalid: Internal Validity Indexes for Fuzzy and Possibilistic Clustering

Compute all of the internal indexes

Description

Computes all of the internal indexes included in the package fcvalid.

Usage

allindexes(x, u, v, m, t=NULL, eta, tidx="f")

Arguments

x	an object of class ‘ppclust’ containing the clustering results from a fuzzy clustering algorithm in the package ppclust. Alternatively, a numeric data frame or matrix containing the data set.
u	a numeric data frame or matrix containing the fuzzy membership values. It should be specified if x is not an object of ‘ppclust’.
v	a numeric data frame or matrix containing the cluster prototypes. It should be specified if x is not an object of ‘ppclust’.
t	a numeric data frame or matrix containing the cluster prototypes. It should be specified if x is not an object of ‘ppclust’ and the option e or g is assigned to tidx.
m	a number specifying the fuzzy exponent. It should be specified if x is not an object of ‘ppclust’.
eta	a number specifying the typicality exponent. It should be specified if x is not an object of ‘ppclust’ and tidx is either e or g.
tidx	a character specifying the type of index. The default is ‘f’ for fuzzy index. The other options are ‘e’ for extended and ‘g’ for generalized index.

Value

idx	fuzzy index values if tidx is ‘f’
idx.e	extended index values if tidx is ‘e’
idx.g	generalized index values if tidx is ‘g’

Examples

# Load the dataset iris and use the first four feature columns 
data(iris)
x <- iris[,1:4]

# Run FCM algorithm in the package ppclust 
res.fcm <- ppclust::fcm(x, centers=3)

# Compute the indexes using res.fcm, which is a ppclust object
idx <- allindexes(res.fcm)
print(idx)
 
# Run UPFC algorithm in the package ppclust 
res.upfc <- ppclust::upfc(x, centers=3)
# Compute the generalized indexes using res.upfc, which is a ppclust object
idx <- allindexes(res.upfc, tidx="g")
print(idx)
