gmmkmsock:

Description

perform k-means specifically designed for a set of GMM (see references). At each iteration, sends information about current prototypes to a server via a socket connection (see references) for info about protocol.

Usage

gmmkmsock(models, names, ngroups, rho = new.env(), host = "127.0.0.1")

Arguments

models

list of GMM objects.

names

character vector with respective names of the GMM objects.

ngroups

(maximal) number of clusters.

rho

R environment object, used for calls to R functions within C code.

host

IP address of the server for the socket (port 1979).

Value

a set of GMM prototypes, and inferred labels (i.e. associated to the input objects).

Examples

temp1 <- sample(1:200, 150)
temp2 <- list()
for(i in 1:length(temp1)) temp2 <- appendToList(temp2, imgmods[[temp1[i]]])
temp3 <- imgnames[temp1]
# next command may be executed only if a server is running on 127.0.0.1:1979.
# temp4 <- gmmkmsock(temp2, temp3, 5)
