Normalized Mutual Information of Community Structure in Network
Description
Calculates the normalized mutual information (NMI) of two community structures in network analysis.
Usage
NMI(X,Y)
Arguments
X |
a data frame or matrix whose first column is the node id and the second column is module |
Y |
a data frame or matrix whose first column is the node id and the second column is module |
Value
value |
value of NMI |
Examples
# Suppose X and Y are exactly the same
X<-data.frame(c(1,2,3),c(2,1,1))
Y<-X
# There NMI is 1
NMI(X,Y)
# Suppose X and Y are completely independent
X<-data.frame(c(1,2,3),c(2,1,1))
Y<-data.frame(c(5,6,7),c(2,1,1))
# There NMI is 0
NMI(X,Y)
